Description
Technical Field
The invention relates to the field of surgery specimen taking, in particular to a device for taking a surgery specimen through a natural cavity.
Background
The laparoscopic surgery is widely used in various large abdominal surgeries and is normalized gradually, but an incision is still needed to be made in the abdomen to take out a specimen. In recent years, a new technology NOSES (operation of taking a specimen through a natural orifice) is developed, the specimen can be taken out through the natural orifice (anus, vagina and the like) by adopting the operation mode, an auxiliary incision is not needed to be made on the abdomen, the minimally invasive advantage is further sublimated, the recovery of the incision of a patient after the operation is facilitated, the patient can get out of bed as soon as possible, expectoration is achieved, and the postoperative recovery is greatly promoted. However, the surgery mode also has some disadvantages:
1. most of the prior art are small incisions made in the vagina or anus, and the specimens are taken out from the incisions, so that the specimens are easily violently pulled or directly contacted during the taking process, tumor cells are shed and planted in the abdominal cavity or the incisions, and the tumor is caused to relapse.
2. The gastrointestinal specimen of some patients has overlarge volume (the fat mesentery of the obese patients excessively creeps and grows, the diseases, the obstruction and other reasons are excessively enlarged), so that important structures such as vagina, rectal mucosa, anal sphincter and the like are damaged in the process of taking out the gastrointestinal specimen from the natural orifice
3. At present, a part of natural orifice protective sleeve devices also appear clinically, but the devices only can protect the natural orifice and cannot ensure the implantation in the abdominal cavity (the inner opening or the cut part of the protective sleeve can inevitably press tumor tissues to cause part of tumor cells to fall off in the abdominal cavity in the taking-out process). In addition, a protective sleeve device needs to be installed firstly, so that certain operation time is prolonged.
Disclosure of Invention
In order to solve the problems in the prior art, the invention aims to provide a device for taking a surgical specimen through a natural orifice, which can wrap and compress tissues while grabbing, thereby reducing friction when passing through the orifice and having good market application prospect.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a device for taking operation samples through a natural cavity comprises a control device and a gripping device:
the control device is hinged with the grabbing device through a hollow connecting rod, a through sliding groove is formed in the middle of the connecting rod, an axially movable control handle is arranged in the sliding groove, and the hinge seat is driven to move back and forth to control the grabbing device to be opened and closed through the sliding of the control handle in the sliding groove;
the grabbing device is in a claw-shaped structure formed by a plurality of scattered grabs, each grab consists of a first knuckle and a second knuckle which are hinged end to end, a connecting rod is hinged to the middle of the first knuckle, a control handle is hinged to the end of the first knuckle, the length of the control handle is longer than that of the connecting rod, a spring is sleeved outside the control handle between the control handle and the hinged portion of the connecting rod, a protective sleeve is sleeved on the second knuckle of the grabbing device, the protective sleeve is sleeved into the corresponding position of the second knuckle and is arranged to be double-layered, the inner layer is completely closed, a fixing piece of the second knuckle and the protective sleeve is arranged on the outer layer, and the plurality of second knuckles are bent inwards at a certain angle and can be touched after being tensioned;
the protective sheath tip is longer than the second knuckle, has embedded the stay cord that can tighten up the protective sheath mouth at its tip, and the stay cord passes through the spout and connects the control handle, and the protective sheath is taut in the pulling through the control handle.
Furthermore, a handle convenient to pull is arranged at the far grab hand end of the control handle.
Further, the pull rope sequentially passes through the head ends of the plurality of second knuckles.
Furthermore, the number of the grippers is 3-5.
Further, the gripping device is made of one of medical rubber, medical plastic or medical metal.
Further, the protective sleeve is 1-2cm higher than the second knuckle.
Furthermore, the first knuckle and the second knuckle are hinged through a pin shaft.
Furthermore, the gripping device and the protective sleeve are cylindrical in appearance, and one end of the gripping device and one end of the protective sleeve can be arranged to be blunt so as to be conveniently inserted into a vagina; the cylindrical passage is internally hidden with a protective bag device.
Compared with the prior art, the invention has the beneficial effects that:
1. the device integrates the gripping device and the protective sleeve device, saves the process of mounting the protective sleeve and saves the operation time
2. The specific shape of the grasping hand of the device can compress the specimen to a certain degree, for example, as shown in figure four (the specimen with the diameter of 5-6cm can be compressed to 3-4cm through the closed diameter of the grasping hand), and the protective sleeve with the lining is used for protection in the compression process, thereby avoiding the falling-off planting of tumor cells in the compression process
3. The gripping device is specially designed into a space similar to a cylinder shape in the opening state, the space is more consistent with the actual shape of the specimen, especially the intestinal specimen can be placed in the protective sleeve along the longitudinal axis, the specimen cannot be accumulated in the protective sleeve to be spherical due to overlarge, the cross sectional area is increased, and finally the incision has to be prolonged for taking out; the cylindrical space is designed to just meet the habit of taking out the longitudinal axis of the intestinal tract, the putting and the compression are carried out by the longitudinal axis, and the intestinal tract can be taken out along the longitudinal axis of the intestinal tract only by making a small incision.
4. Forming multilayer protection, wherein the protective sleeve is 1-2cm higher than the tip of the gripper, the gripper is closed to drive the protective sleeve to be closed to form first layer protection, and the protective sleeve opening is tightened to form second layer protection; the possibility of cell shedding, planting and transferring during the taking-out process is avoided to a greater extent.
5. The sample volume is compressed to a certain degree, the volume is smaller when the sample is taken out, and the extrusion damage to a natural cavity is reduced.
6. The grip configuration and dimensions of the device may be designed for different specimens and sizes, for example, as shown in the following figures.
