Description
Technical field
The utility model relates to medical suturing skill field, in particular to a kind of anorectal anastomat with limiting device.
Background technique
In present PPH operation, the flexible handle that needs manually to hold with a firm grip after stapler percussion keeps stapler to be in closed form
State at least 30 seconds or more, doctor was inconvenient, if doing within doctor one day more operations, increases the feeling of fatigue of personnel, is in addition also easy
Flexible handle is unclamped in advance causes certain risk.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, and it is identical to provide a kind of anal intestine with limiting device
Device.
The utility model solves technical solution used by prior art problem: a kind of anal intestine with limiting device is identical
Device, including shell, the shell is interior to be equipped with straight push rod, and the shell is equipped with flexible handle, the flexible handle and straight push rod
Connection, the flexible handle drive straight push rod to move forward and backward, and the rear end of the shell is equipped with adjusting nut, and the anal intestine is coincide
Device further includes limiting device, and the limiting device includes limit button and compressed spring, and the compressed spring is located at limit button
On the boss of front end, the straight push rod is equipped with the limit card slot to match with the boss of the limit button.
Further, the front end of the flexible handle of the shell is equipped with link block, and the straight push rod is equipped with and link block
The groove of connection.
Further, torsional spring, when hand does not press flexible handle, flexible handle are equipped with inside the flexible handle of the shell
Original state is maintained under the effect of torsional spring elastic force.
The utility model has the beneficial effects that:
The utility model is simple and practical in structure, without continuing the flexible handle long period of manually holding with a firm grip, alleviates doctor's
Labor intensity reduces the risk of operation.
Detailed description of the invention

Fig. 2 is the structural schematic diagram of the utility model limiting device.
In figure: 1, shell, 2, straight push rod, 2.1, limit card slot, 3, flexible handle, 4, adjusting nut, 5, limiting device,
5.1, limit button, 5.2, compressed spring, 5.3, boss, 6, reset spring, 7, groove.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Embodiment one
A kind of anorectal anastomat with limiting device as shown in Figure 1 to Figure 2, including shell 1 are set in the shell 1
There is straight push rod 2, the shell 1 is equipped with flexible handle 3, and the flexible handle 3 is connect with straight push rod 2,3 band of flexible handle
It moves straight push rod 2 to move forward and backward, the rear end of the shell 1 is equipped with adjusting nut 4, and the anorectal anastomat further includes limiting device
5, the limiting device 5 includes limit button 5.1 and compressed spring 5.2, before the compressed spring 5.2 is located at limit button 5.1
On the boss 5.3 at end, the straight push rod 2 is equipped with the limit card slot 2.1 to match with the boss 5.3 of the limit button 5.2.
It is equipped with link block in the front end for being embedded in the flexible handle 3 of the shell 1, straight push rod 2 is equipped with and connect with link block
Groove 7.
Torsional spring is equipped with inside the flexible handle 3 of the shell 1, when hand does not press flexible handle 3, flexible handle 3 is being turned round
Original state is maintained under spring force effect.
The rear end of the straight push rod is equipped with reset spring 6.
The working principle of the utility model is as follows:
In percussion, doctor presses flexible handle 3, moves forward straight push rod 2, and pushing slice of nail and endless knife is pushed to be fired into
Position, limit button 5.1 is fallen under the action of 5.2 elastic force of compressed spring in the corresponding limit card slot 2.1 of straight push rod 2 at this time, this
When can unclamp flexible handle 3, instrument locks state of pressure keeping (as shown in Figure 2) still in percussion.
When needing to be reset the arrival dwell time, reset button 5.1 need to be only lifted upwards, unclamp flexible handle 3, movable hand
Handle 3 resets under the action of torsional spring elastic force, while straight push rod 2 moves backward under the drive of flexible handle 3, and instrument can reset
To original state.
Specific case used herein is expounded the principles of the present invention and embodiment, above embodiments
Explanation be merely used to help understand the method and its core concept of the utility model.It should be pointed out that for the art
For those of ordinary skill, under the premise of not departing from the utility model, can also to the utility model carry out it is several improvement and
Modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
