Abstract
The utility model discloses an adjusting handle for a tube-type stapler. The adjusting handle for the tube-type stapler comprises a handle cover, a nut adjusting handle and a screw rod with multi-stage threads, wherein the screw rod with the multi-stage threads penetrates the nut adjusting handle and is threadedly matched with the nut adjusting handle; the adjusting handle further comprises clamping pressing plates, the handle cover is arranged at one end of the nut adjusting handle in a sleeve mode, the clamping pressing plates are arranged between the handle cover and the nut adjusting handle, and the clamping pressing plates are axially arranged on the nut adjusting handle. Therefore, the adjusting handle for the tube-type stapler can effectively prevent looseness of tissue clamping during the firing of the staple through the clamping after the nut handle and the screw rod of the adjusting handle are matched, and avoids affecting stapling and cutting effect of tissue.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of regulating handle for tube type anastomat.
Background technology
Various Digective canal tubular anastomats just are being widely used in coincided with human body digestive tract tissue in surgical operation, can reduce operating time, improve the operation quality.They are normally used for the end ends such as esophagus in digestive tract, Stomach duodenum, small intestinal, coton and rectal, distolateral and side to side anastomosis operation, be specially adapted to appear and the operations such as the esophagus end to end anastomosis at the stomach breast top of operating difficulties and low rectal carcinectomy postcolon rectum low level end to end anastomosis, also be applicable to Haemorrhoids cutting stomach function regulating pylorus and make and mouthful wait an operation that forms tubular passageway in organ.The regulating handle of existing tube type anastomat makes front end apparatus grasping tissue by rotary handle, regulating handle is the effect that the precession process plays a transmission, do not prevent the function of convolution after being rotated in place, therefore exist following not enough when the handle of tube type anastomat of the prior art is used: apparatus tightens up rear regulating handle and does not prevent rotating design, in the situation that likely stressed at front end in apparatus percussion process, regulating handle turns round, and making coincide and cut does not make operative failure fully.
The utility model content
For above-mentioned deficiency of the prior art, this utility model main purpose is to provide a kind of regulating handle for tube type anastomat, can by the nut handle on regulating handle be tightened onto front end apparatus clamping tight after, eliminate in the gap of regulating handle and fixed handle, after fixed handle produces active force to the resistance backing plate, the clamping pressing plate produces the screw mandrel in the middle of the active force fixed bit, thereby prevented the rotation between screw mandrel and regulating handle, effectively prevent that anastomat tissue clamping when percussion from getting loose, and avoids the osculating effect of impact tissue.
For achieving the above object, the technical solution adopted in the utility model is: a kind of regulating handle for tube type anastomat, comprise: handle cover, nut regulating handle, multistage thread screw, described multistage thread screw run through described nut regulating handle and with described nut regulating handle threaded engagement; Described regulating handle also comprises the clamping pressing plate, and described handle cover is sheathed on an end of described nut regulating handle, and described clamping pressing plate is located between described handle cover and described nut regulating handle, and described clamping pressing plate shaft is located on described nut regulating handle.
Preferably, described handle cover is hollow structure, an end closure, other end opening; The closing end of described handle cover is provided with a stop nut, and described stop nut is located between the end wall and described multistage thread screw of described handle cover closing end.The effect of the stop nut described in this utility model is spacing that the middle screw mandrel in tube type anastomat is regulated, and prevents stroke and damages regulating handle.
Preferably, described multistage thread screw is divided into three sections, is respectively: the first thread segment, the second thread segment, the 3rd thread segment, and the flight pitch on described the first thread segment, the second thread segment and the 3rd thread segment is all different; Described multistage thread screw rear end is provided with the screwed hole in an axle center perpendicular to described multistage thread screw.The screwed hole that in this utility model, multistage thread screw is provided with is the restriction for the location to multistage thread screw and stroke.In this utility model, multistage thread screw is divided into to three sections, the different purpose of flight pitch is in order to reach fast thread and the switching between screw thread at a slow speed, shortens the apparatus operating time.
Preferably, also comprise a screw rod helical pitch pin and a helical pitch pin ring for fixing, described nut regulating handle is provided with a helical pitch pin-and-hole, and described screw rod helical pitch pin matches with described helical pitch pin-and-hole; Described helical pitch pin ring for fixing is fixed on the outer wall of an end that the nut regulating handle is provided with the helical pitch pin-and-hole.The effect of the helical pitch pin ring for fixing described in this utility model is that assurance screw rod helical pitch pin is located reliably, in actual instrumentation, screw rod helical pitch pin plays the quick precession of front end in apparatus precession process, and the head end screw thread that is switched to multistage thread screw in the apparatus grasping tissue is connected with the reliable of left side screw thread of nut regulating handle.
The beneficial effects of the utility model are: this utility model can be by the nut handle on regulating handle and clamping after screw rod coordinates, and the working end grasping tissue that effectively prevents anastomat gets loose while coincideing cutting, the osculating effect of impact tissue.
