Description
Technical Field
The utility model relates to medical equipment, in particular to a disposable intestinal canal lifting fixer.
Background
The laparoscopic rectal cancer operation has some technical problems, namely, the number of parts is large, and the locking mode is assisted, so that the production cost is increased;
when the movable end of the strapping tape passes through the locking channel to be locked, the strapping tape does not have single directivity, namely, the movable end of the strapping tape can pass through any end of the locking channel, and when the direction passing through the locking channel is wrong, the strapping device cannot play a role in locking;
and the linear strapping tape is not matched with the appearance of the organ to be fixed.
The head of the lock catch is not provided with a structure which is convenient for clamping and preventing slipping of the apparatus;
after the organ is bound and lifted, the binding locking bulge is blocked and not firm with a tooth slot on the binding belt body, and can be loosened in the process of forcefully lifting the lock catch head, so that the lifting effect is reduced;
therefore, aiming at the technical problems, the Chinese patent ZL202020276885.9 discloses a medical-grade viscera-binding lifter, which better solves the problems. However, in practical applications, the device has the following disadvantages:
1. the bundling blocking effect is formed by inserting the movable end of the bundling belt body into the bundling lock catch to finish self-locking, but in the process that the bundling lock catch is placed into the abdominal cavity through the abdominal wall puncture sleeve, the head of the bundling lock catch is excessively large (as shown in fig. 1-2), so that the bundling lock catch is possibly blocked when passing through the abdominal wall puncture sleeve with smaller specification, thereby affecting the operation time, and ensuring the operation effect;
2. the head of the existing disposable intestinal canal lifting fixer is cylindrical, and the head is easy to slip and not to grasp when being grasped by an instrument clamp, so that the operation time is prolonged, and the operation effect is affected;
in summary, how to avoid interference of the device when passing through the puncture cannula is an urgent problem to be solved by researchers in the field.
Disclosure of Invention
The utility model aims to solve the technical problems that: how to avoid interference of the device when passing through the puncture cannula;
in order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model is a disposable intestinal canal lifting fixer, comprising: the rear part of the first part is fixedly connected with one end of the brace; the front part of the second part is fixedly connected with the pull ring; a connecting column connecting the first and second parts located at the upper and lower positions; the front-back length of the first part and the second part is larger than the left-right width;
the front and back length of the first part and the second part of the traditional cylindrical structure is equal to the left and right width, so that the device interferes with the puncture cannula due to the limitation of the width direction when the first part and the second part pass through the puncture cannula;
in the scheme, the front-back length of the first part and the second part is larger than the left-right width, so that the widths of the first part and the second part are correspondingly reduced compared with the conventional device, and the first part and the second part can penetrate through the puncture cannula to avoid interference between the first part and the second part.
In order to explain the specific structure of the first part and the second part, the utility model adopts the structure that the cross section shapes of the first part and the second part are consistent and are elliptical;
by arranging the first part and the second part into an ellipse, the major axis of the ellipse is the length direction of the first part and the second part, the minor axis of the ellipse is the width direction of the first part and the second part, and the first part and the second part of the ellipse are designed as round angles, so that the puncture cannula is not cut;
in addition, the penetration of the device through the puncture cannula may be facilitated by reducing the thickness of the first portion.
In order to avoid the situation that an operator uses an instrument clamp to grasp the device and skid, so that the operation time is prolonged and the operation effect is affected, the utility model adopts the structure that anti-skid convex points are arranged on the left side and the right side of a first part or a second part;
through setting up anti-skidding bump increase with the frictional force of apparatus pincers, the phenomenon of skidding can not take place, takes out this device with stability.
The utility model has the beneficial effects that: the utility model relates to a disposable intestinal canal lifting fixer, wherein a first part and a second part of the device are elliptical, the thickness of the first part is reduced, and anti-skid convex points are arranged on the side surface, so that the device can conveniently pass through a puncture sleeve and increase the friction force with an instrument clamp; avoiding interference of the device when passing through the puncture cannula.
