Abstract
The utility model relates to a surgical instrument which is applied to expanding sub-scalp soft-tissue spaces during a ventriculo-peritoneal shunt. A sub-scalp soft-tissue space expander is divided into two left and right parts and three front and rear parts, wherein the two left and right parts and the three front and rear parts can be disassembled, and the latter comprises a front expanding part, a rear expanding part, a connecting part and a holding part, wherein the connecting part is provided with an upper bayonet and a lower bayonet, and the holding part is provided with two fork-shaped metal sheets. The front expanding part is protected by the upper bayonet and is closed into the shape of a round barrel which has the inner diameter of 3.5mm and the outer diameter of 4mm, is hollow and can sleeve a cleaning rod used by the shunt under the elastic action of the two fork-shaped metal sheets of the holding part in a closed state that the holding part is loosened, and the front expanding part is limited by the lower bayonet of the connecting part in an opening state that the holding part is tightened, and can reach the max width of 5cm; the rear expanding part is expanded into an ellipse and can be used for allowing the cleaning rod or other apparatuses to pass. In the shunt, the front expanding part is firstly closed, sleeves a cleaning-rod body part which passes through the sub-scalp soft-tissue space and one end of which is exposed outside scalp, then slides into the gap therewith and slides into the gap after being expanded, the whole operation is repeated , until surgical requirements are met, so that the sub-scalp soft-tissue space expander has the advantages of convenience in operation, small wound and reliable effect.
Description
Technical field
This utility model relates to medical instruments field, is a kind of operating theater instruments hydrocephalic ventriculoperitoneal shunt for the treatment of, an expansion sub-dermal soft tissue gap that is applied to.
Background technology
Ventriculoperitoneal shunt is hydrocephalic a kind of therapeutic method of surgery.In this art, need first to expand a sub-dermal soft tissue gap, i.e. galea aponeurotica lower floor and/or periosteum lower floor, then isocon pump and reservoir are imbedded in this gap.At present, to use common vascular forceps to carry out dilation procedure clinically, not only operation inconvenience, wound are large, and the layer of structure mistake that is prone to expansion gap causes isocon pump and reservoir to imbed difficult problem, but still there is no a kind of easy and reliable operating apparatus.
Summary of the invention
For overcome existing operating theater instruments deficiency, reduce operation wound, the purpose of this utility model is to provide in a kind of ventriculoperitoneal shunt simple in structure, easy to operate, reliable for effect the operating theater instruments in an expansion sub-dermal soft tissue gap.
This utility model solves the technical scheme that its technical problem adopts: in structure, be divided into two of left and right, three of front and back, wherein, two of left and right are disassembled, and three of the front and back of every comprise enlarged portion, connecting portion, grip part.Enlarged portion is positioned at front, is divided into expansion front portion and expansion rear portion; Connecting portion, in centre, comprises that connecting axle, fixed screw, upper and lower bayonet socket connect, and two of left and right are connected, assemble, fix, worked by connecting portion; Holding area is in rear, and centre is done elasticity with corresponding two fork-shaped sheet metals difform, that lay respectively at two of left and right and is connected and fixed.The expansion front portion that left and right is two is subject to the protection of connecting portion upper latch notch, borrow two fork-shaped sheet metals elastic force effect, under the closure state that unclamps grip part, close up for internal diameter 3.5mm, external diameter 4mm, hollow, just can entangle the barrel-shaped of bypass poker used, be subject to the restriction of bayonet socket under connecting portion, under the open configuration that tightens up grip part, the widest 5cm that reaches of front end; Ovalize is expanded at the expansion rear portion of two, left and right, can hold the poker or other apparatuses that stretch into.In ventriculo-peritoneal shunt, first unclamping grip part makes to expand anterior closed and entangle and navigate within a sub-dermal soft tissue gap and one end exposes to the poker body of scalp, take advantage of a situation again and slip into a sub-dermal soft tissue gap along poker, tighten up grip part, after a sub-dermal soft tissue gap is opened and expanded to enlarged portion, more closed enlarged portion and along poker continue slip into deep, so repeatedly, until reach the requirements of operation of inserting isocon pump and reservoir, finally exit from original route.
The beneficial effects of the utility model: for the problem in an expansion sub-dermal soft tissue gap in hydrocephalus ventriculoperitoneal shunt, provide a kind of operating theater instruments, operation technique simplification, accuracy, wound have been minimized, and reliable for effect.
Brief description of the drawings
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is apparatus overall schematic of the present utility model;
Fig. 2 is that apparatus of the present utility model is disassembled and front end schematic cross-sectional view.
1. expansion front portions in figure, 2. expansion rear portion, 3. connecting portion, 4. grip part, 5. fork-shaped sheet metal, 6. screw.
Detailed description of the invention
A sub-dermal soft tissue gap dilator is divided into three parts as shown in Figure 1, and one is expansion anterior (1) and expansion rear portion (2), and it two is connecting portion (3), comprises connecting axle, fixed screw and bayonet socket up and down thereof; It three is grip part (4), comprises two the cross-coupled corresponding difform fork-shaped sheet metal of energy (5) and fixed screws (6) thereof that lay respectively at two of left and right.In the time unclamping dilator grip part (4), the elastic force effect of two fork-shaped sheet metals (5) is borrowed in the expansion front portion (1) that left and right is two under the protection of connecting portion (3) upper latch notch, just also can entangle the poker using in bypass in complete closure state.In the time tightening up grip part (4), expansion anterior (1) open the restriction that is subject to bayonet socket under connecting portion (3), the widest 5cm that reaches.So, in the time that poker in bypass has navigated within a sub-dermal soft tissue gap, expansion of the present utility model anterior (1) can be overlapped on the poker body that at one end exposes to scalp, unclamp with grip part (4), tighten up alternately and coordinate, take advantage of a situation and slide, go deep into, expand a sub-dermal soft tissue gap, make this gap can hold lower shunt tube pump and reservoir, exit from original route after reaching requirements of operation, easy and simple to handle, clear in structure and wound minimum.
Three of two of the left and right of a sub-dermal soft tissue gap dilator after disassembling and front and back as shown in Figure 2.Wherein, expand anterior front end transverse section and illustrate its internal diameter 3.5mm, external diameter 4.0mm; Two fork-shaped sheet metal side views signal shapes are consistent, but front view illustrates that its head end can corresponding connection and shape is inconsistent.
