Abstract
The utility model discloses a neurosurgery scalpel, and relates to the technical field of neurosurgery medical apparatuses and instruments. The neurosurgery scalpel comprises a scalpel body and a scalpel handle and further comprises a push rod and a wedge-shaped pressing plate. The push rod is placed in the scalpel handle, and a reset spring is arranged between the scalpel handle and the push rod. The outer end of the push rod is fixedly connected with the scalpel body, and the inner end of the push rod is rotatably connected with two symmetrically-arranged dragging wheels with the axial direction being perpendicular to the push rod. The two dragging wheels are both placed in the inside space of the wedge-shaped pressing piece, and the length of the wedge-shaped pressing piece is larger than the length of the scalpel handle. Only when the neurosurgery scalpel is held by medical staff, the scalpel body can extend from the scalpel handle, and the medical staff is prevented from being hurt.
Description
Technical field
This utility model relates to neurosurgery technical field of medical instruments.
Background technology
At present, the scalpel that clinician uses in the time doing neurosurgery is mainly made up of cutter hub and handle of a knife, and handle of a knife is thinner, and surface smoothing, in operation process, be easy to come off in hands, thereby cause malpractice, increased work difficulty to medical worker.And, medical nerve surgical knife, great majority do not have safety guard, and blade is exposed, very easily hurts medical worker and cleanup crew, the threat that easily causes medical worker and cleanup crew's blood-borne pathogens to infect.In operation application, scalpel may surprisingly be cut brokenly doctor's finger, or cuts brokenly the finger of other aid workers in nurse and operating room.Equally, in the time that scalpel transmits between surgical staff, surgical staff also may be by accidental cuts.
Chinese utility model patent (patent No. is CN202821539U) discloses a kind of retractable safety scalpel, and it is made up of overcoat, knife rest, trivial key, several parts of spring.Knife rest holddown groove, trivial key sliding tray, trivial key fixing hole, spring stop are put outward; On knife rest, have trivial key, trivial key links together by spring leaf and knife rest, and knife rest afterbody has spring and spring locking cap.Spring leaf one end is welded on knife rest, and the other end is welded on trivial key.When medical personnel use this scalpel, promote trivial key to trivial key fixing hole place, expose blade, clutch trivial key, use scalpel.Finish using, unclamp trivial key, trivial key is upspring automatically, the effect bottom knife of spring with knife rest retraction overcoat in, reach protection medical worker's object, and easy, Yi Hang, safety, reliably.Can effectively solve the exposed easy incised wound medical worker of current scalpel blade and cleanup crew's problem.But in actual operation application, medical personnel promote locking key along the length direction of handle of a knife, can only could be regained after operation finishes, and cannot avoid may causing the injury to medical worker in operation process.
Utility model content
Technical problem to be solved in the utility model, be the technical deficiency for above-mentioned existence, provide a kind of property easy to use, safe strong neurosurgery scalpel, only in the time that medical personnel hold, cutter hub just can stretch out from handle of a knife, can avoid medical personnel to receive injury.
The technical solution adopted in the utility model is: a kind of neurosurgery scalpel is provided, comprises cutter hub and handle of a knife, also comprise push rod and wedge shape tabletting, push rod is positioned at handle of a knife inside, and is provided with back-moving spring between handle of a knife and push rod; Outer end and the cutter hub of push rod are fixed, and inner end is rotatably connected to axially and symmetrically arranged two drag wheels vertical with push rod; Described two drag wheels are all positioned at the inner space of wedge shape tabletting; The length of wedge shape tabletting is greater than the length of cutter hub.
Further optimize the technical program, two surfaces in neurosurgery scalpel wedge shape tabletting outside are provided with anti-slip veins.
Further optimize the technical program, the back-moving spring of neurosurgery scalpel is stage clip, and the opening of stage clip one end and handle of a knife is fixed; The other end of stage clip and the inner end of push rod are fixed.
Further optimize the technical program, two surfaces of the wedge shape tabletting inner side of neurosurgery scalpel have gathering sill.
The beneficial effects of the utility model are: 1, stretching out of cutter hub is to be gripped and pressed that the mode of wedge shape tabletting realizes by medical personnel, and gathering of wedge shape tabletting directly acts on two drag wheels, and two drag wheels are released cutter hub by push rod from handle of a knife; In the time that medical personnel unclasp wedge shape tabletting, two drag wheels are regained handle of a knife by push rod by cutter hub under the effect of back-moving spring, have immediately guaranteed that cutter hub does not contact with medical personnel under non-working condition, prevent the injury of cutter hub to medical personnel; 2, anti-slip veins can increase the frictional force of this utility model and medical personnel's hands, is convenient to medical personnel's use.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that removes handle of a knife and wedge shape tabletting in Fig. 1;
Fig. 3 is the structural representation of wedge shape tabletting in Fig. 1.
In figure, 1, cutter hub; 2, handle of a knife; 3, push rod; 4, wedge shape tabletting; 5, back-moving spring; 6, drag wheel; 7, anti-slip veins; 8, gathering sill.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Shown in Fig. 1, Fig. 2 and Fig. 3, neurosurgery scalpel, comprises cutter hub 1 and handle of a knife 2, also comprises push rod 3 and wedge shape tabletting 4, and push rod 3 is positioned at handle of a knife 2 inside, and is provided with stage clip between handle of a knife 2 and push rod 3; The opening of stage clip one end and handle of a knife 2 is fixed; The inner end of the other end of stage clip and push rod 3 is fixed; The outer end of push rod 3 and cutter hub 1 are fixing, and inner end is rotatably connected to axially and symmetrically arranged two drag wheels 6 vertical with push rod 3; Described two drag wheels 6 are all positioned at the inner space of wedge shape tabletting 4; The length of wedge shape tabletting 4 is greater than the length of cutter hub 1; Two surfaces in wedge shape tabletting 4 outsides are provided with anti-slip veins 7; Two surfaces of wedge shape tabletting 4 inner sides have gathering sill 8.
Two drag wheels 6 are arranged in the gathering sill 8 of wedge shape tabletting 4, and when wedge shape tabletting 4 is squeezed, the pressure that two drag wheels 6 are subject to is decomposed into another power of power of vertically-guided groove 8 and the length direction of handle of a knife 2.Push rod 3 is moved in trying hard to recommend of handle of a knife 2 length directions, overcomes the elastic force of back-moving spring 5; Cutter hub 1 is released from handle of a knife 2; This structure grips the using state of scalpel according to medical personnel, realized the instant folding and unfolding of cutter hub 1, can not damage medical personnel.
