Description

Circumcision Stapler

technical field

The invention relates to a medical device, in particular to a circumcision and stapler.

Background technique

At present, there are three kinds of circumcision surgery. 1. Traditional circumcision surgery. This surgical method requires high clinical experience of doctors. The operation is cumbersome and takes a long time. A little carelessness will cause excessive bleeding, uneven incision, and wound suture It is not beautiful, and it is also very troublesome to change the dressing and remove the stitches after the operation. 2. Laser or electric knife surgery often causes scorching of the foreskin, long postoperative recovery time, and high incidence of hematoma. 3. With the help of ligation with small instruments, the foreskin will fall off due to ischemic necrosis. This operation method takes a long time to recover after operation, and it is necessary to wear equipment for a period of time, which makes life inconvenient and prone to complications.

In order to improve the deficiencies of the above operations, a circumcision stapler has appeared in recent years, although the existing circumcision stapler has completed excision and suturing simultaneously, and has the advantages of short operation time and less bleeding. However, due to the short development time and immaturity of the product, there are still many defects in the structure and other aspects. It is mainly reflected in the unreasonable setting of the overall structure and the matching structure of each component, and the complicated process. If the ring knife is installed on the corresponding nail push piece by assembling in the form of an independent split part, it may cause problems such as skew, misalignment, and poor welding during the installation process, resulting in deflection during the operation, the knife comes off, or even Risk of not being able to cut sutures. Moreover, the existing circular knife is long and installed at the bottom of the pusher plate, so the visibility is poor, and the operator cannot see the cut tissue site clearly, and often cuts the frenulum site of the foreskin by mistake, which increases the risk of surgery.

The staple cartridge and the staple cartridge cover are assembled into a staple cartridge assembly, and its main function is to accommodate preloaded staples. The number of staples is required to be complete during the operation. If there is leakage, bleeding will easily occur at the leakage site after suturing, which will affect the surgical effect.

The existing staple cartridge components are all made of opaque materials, which results in a large workload and low efficiency for checking missing staples. During inspection, the staple tip needs to be pushed out of the staple cartridge, and after the inspection is completed, the staple needs to be pushed to the bottom of the staple cartridge. The inspection efficiency is low and the operation risk is high.

The glans sleeve used in the existing circumcision and suturing devices is made of plastic, and the nailing seat is made of metal. The nailing base is easy to fall off from the glans sleeve. When used in large sizes, it is easy to deform or even break, resulting in loose suture bleeding or failure to suture . Moreover, the glans condom is a slot-type design with one end open, and the patient may feel uncomfortable after the glans is placed in the glans condom due to its closed design.

Utility model content

The purpose of this utility model is to provide a kind of foreskin cutting and suturing device aiming at the above-mentioned deficiencies in the prior art. The foreskin cutting and suturing device has simple, scientific and reasonable structure, simple manufacturing process, simple and convenient installation and use.

The technical scheme of the foreskin cutting and suturing device includes a nail block assembly, a staple set in the staple cartridge, a staple cartridge cover, a force device connected to the staple cartridge cover, and a push nail provided in the staple cartridge cover. body, and an annular knife located on the pusher body; the pusher body includes a pusher seat, a number of pusher sheets arranged on the pusher seat, a bracket, and a bracket connected between the pusher seat and the bracket The guide sleeve, the nail anvil assembly includes a glans glans and a nail anvil, at least two semicircular positioning grooves are formed around the nail anvil, and the glans glans is provided with at least two corresponding semicircular positioning grooves. The positioning column, the glans penis and the nail abutment seat are snap-fitted and connected to each other through the semicircular positioning post and the corresponding semicircular positioning groove, and the nail anvil is also provided with nail holes uniformly distributed along the circumferential direction.

The boosting device includes a boosting handle and a cylindrical guide body that are respectively movably and fixedly connected to the staple cartridge sleeve.

The cylindrical guide body includes two cover plates axially symmetrically connected to each other.

The booster handle of the booster has anti-skid dots, and there are more than two rows of anti-slip dots.

Because the staple cartridge cover, staple cartridge and/or push nail body are transparent, the circumcision and stapler has a better line of sight and a shorter ring knife, so the operation process of the cutting device can be observed in the whole process, which is helpful for grasping and controlling the implementation of the operation. Whether the staples are missing or not can be directly visually inspected, which improves the inspection efficiency. Before the operation, the doctor can confirm whether the nail is missing, which improves the safety of the operation.

At the same time, the ring knife and the push nail seat or push nail piece are made into an inseparable one-piece structure design, which better ensures the concentricity of the knife and the push nail piece on the premise of ensuring sufficient firmness, and avoids skewing and misalignment when ironing the knife. And other problems, so as to achieve the perfect combination of suture and removal of redundant foreskin and visualization during the operation. In particular, the setting position of the ring knife and the structure are scientific and reasonable, so that there is no invalid stroke and no redundant movement when the ring knife works, and the cutting action process is crisp, neat and accurate.

The anvil and the glans sleeve are made of metal, which avoids the disadvantages that the anvil is easy to fall off from the glans sleeve, and the glans sleeve is easily deformed or even broken, resulting in weak sutures, bleeding or inability to suture.

Ventilation holes are set on the glans sleeve to avoid discomfort caused by the closed design of the patient's glans after being placed in the glans sleeve.
