Circumcising anastomat

Abstract

The invention discloses a circumcising anastomat and belongs to the field of medical surgical instruments.The circumcising anastomat comprises a knife handle, a pushing knife sleeve, a knife shell, a pushing knife disk, a cover type cutting knife, a glans penis cap, a nail containing bin and an adjusting knob, wherein the center of the knife handle is provided with a pushing knife sleeve moving cavity, and the right end of the knife handle is provided with a pair of handle hinge seats; the pushing knife sleeve is arranged in the pushing knife sleeve moving cavity; the knife shell is connected with the right end of the knife handle in a matched mode; the pushing knife disk is contained in a pushing knife disk seat cavity; the cover type cutting knife is contained in a pushing knife disk cavity; the center of the top wall of the glans penis cap is provided with an adjusting screw seat; the nail containing bin is arranged on a nail bending foot ring; the adjusting knob is matched with the knife handle.The circumcising anastomat is characterized by further comprising a knife handle connector, wherein the knife handle connector stretches into the pushing knife sleeve moving cavity from the position corresponding to the left end of the knife handle and is locked to the knife handle, the center of the side, facing the knife handle, of the adjusting knob is provided with a knife handle rear connecting sleeve cavity, and an adjusting screw is connected with the adjusting knob after penetrating through the knife handle connector.The concentricity between the glans penis cap, the pushing knife disk and the knife shell is ensured; the adjusting knob is prevented from separating from and falling off a knife handle rear connecting sleeve; secondary pain of an acceptor is eliminated; a suturing nail is prevented from changing positions; due to front assembling, operation is rapid.

Description

technical field [0001] The invention belongs to the technical field of medical surgical instruments, in particular to a circumcision stapler. Background technique [0002] The "circumcision and stapler" recommended by China Invention Patent Authorization Announcement No. CN101884559B makes up for the utility model authorization announcement No. alloy foreskin cutter), etc., for details, please refer to paragraphs 0002 to 0003 of the description of CN101884559B. Furthermore, the "circumcision and stapler" provided by the invention patent authorization announcement number CN102217969B objectively evaluates the shortcomings of CN101884559B and eliminates them. For details, please refer to paragraph 0003 of the description of CN102217969B. [0003] The above-mentioned technical points of CN102217969B are recorded in the 18th to the 26th lines of paragraph 0009 of the instruction manual. The positive significance of this technical point is that since the guide wings are formed i...

Problems solved by technology

[0004] However, the aforementioned CN102217969B still has the following drawbacks: first, because the adjustment rotation is directly through the narrowing boss at one end and the knob positioning cavity on the pair of handle shell flaps, and because the pair of handle handle shell flaps are matched with each other , so the manufacturing error and the matching error of a pair of handle shell valves (including the face-to-face matching effect of a pair of handle shell valves) will have an impact on the limit of the adjustment knob. The axial movement of the knob is caused by the matching gap between it and the end surface of the aforementioned knob positioning cavity, while the shaking of the adjusting knob is caused by the matching gap between the shell flaps of a pair of handles

Therefore, the axial movement and shaking of the adjustment knob will affect the concentricity among the tortoise bucket cap, the push knife disc and the knife shell, and ultimately make it difficult to achieve the expected effect of the circumcision operation.

Because before the circumcision, the surgeon first puts the glans cap on the subject’s glans, and then turns the redundant foreskin on the subject’s genitals to cover the side of the glans cap facing away from the glans cavity , and then the surgeon operates the adjustment knob, the adjustment knob drives the adjustment screw fixedly connected to the glans cap, and the glans cap is driven by the adjustment screw, forcing the foreskin constraint covering the glans cap to be limited between the cutting edge of the cover-type cutter and the glans cap. between the knife and anvil, so once the adjustment knob moves and shakes, the foreskin ring will undoubtedly be eccentric; second, because a pair of handle shells are used, and because the adjustment knob directly passes through the narrow boss at one end and the The rotation of the knob positioning cavity is also restricted due to the volume of the adjustment knob, so on the one hand, the operation of the surgeon is relatively laborious, especially in the process of operating the adjustment knob or even a slight repulsion of the shell flap by a pair of hands. In some cases, the aforesaid narrowed boss of the adjustment knob will break free from the knob positioning cavity and even fall to the floor, so when the adjustment knob falls to the floor, it can only be used after being disinfected again, which increases the trouble for the surgeon and prolongs the operation time. Operation time; thirdly, due to the incomplete hemostasis after the foreskin incision was completed and the foreskin incision site was sutured by staples at the same time, the staples were enveloped into the tissue, and the incision cracked due to penile erection in the recovery stage Therefore, on the one hand, it will bring troubles to the doctor for follow-up treatment, and on the other hand, it will cause secondary pain to the recipient; fourth, due to the lack of protection measures for the loaded nail cartridge, it will be damaged due to vibration during product transportation. Cause the staples to come out of the staple loading cartridge and / or cause a group of staples spaced apart around the circumferential direction of the staple loading cartridge to be misaligned, so that when one or more staples are missing or misaligned Under the circumstances, there is no doubt that it will have an impact on the suture effect of the incision of the patient; five, because the cross-sectional shape of the adjustment screw seat of the glans cap is generally rectangular and has an adjustment screw seat flange at each of the four corners (ribs), and because the shape of the narrowed adjustment screw seat cavity in the pusher disc cavity of the pusher disc is a rectangular cavity, and an adjustment screw matching the flange of the adjustment screw seat is formed at each of the four corners of the cavity wall. Seat flange (rib) guide groove, so the adjustment screw seat can be matched with the adjustment screw seat cavity only when the adjustment screw seat flange corresponds to the adjustment screw seat flange guide groove. However, due to the lack of A reference datum for rapid alignment, thereby affecting operational efficiency
