Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a guiding strip for a linear cutting stapler in a body cavity. Background Technique

[0002] The intracavitary linear cutting stapler is a medical device used for suturing while cutting in a body cavity. Usually, its working part is a cutting and suturing head, which consists of an anvil, a cartridge, and a cutting knife. Some are equipped with a guide, while some are not. The guide is used to guide the anvil through narrow tissue gaps. The cartridge contains alloy suturing staples. After the jaws of the cartridge and the anvil close to clamp the human tissue, the cutting knife advances forward, and at the same time, the suturing staples in the cartridge will penetrate the human tissue and bend to lock, thus suturing the edges of the incision together.

[0003] At present, there are various guiding heads for intracavitary linear cutting staplers on the market, but most of them are made of hard materials and lack deformability. If the force is not properly controlled during use, it may cause damage to the human tissue structure. The existing guiding heads are designed to bend inward at a certain angle towards the jaws, but this bending angle is immutable, which results in that in most cases, the guiding heads with such bending angles do not meet the angles required by the surgical operator, so they are not practical. Moreover, the guiding head that bends upward reduces the width of the jaws at the head end of the linear cutting stapler, making it more difficult to clamp tissues with a relatively thick thickness. In addition, the existing guiding heads are mainly divided into an integrated anvil head type and a detachable type. The integrated anvil head guiding head is easy to pierce into human tissues or blood vessels, resulting in injury or bleeding. The detachable guiding head needs to enter the body cavity together with the anvil head of the cutting and suturing stapler for operation. If it accidentally falls, due to the characteristics of hard materials, it is very difficult to take out, which may lead to medical accidents. Content of the Utility Model

[0004] The purpose of the utility model is to provide a guiding strip for a linear cutting stapler in a body cavity to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A guiding strip for a linear cutting stapler in a body cavity, comprising:

[0007] A traction rope part;

[0008] A conical cap part, the top of the conical cap part gradually transforms into the traction rope part, and the two are made of the same material and are integrally formed without a clear demarcation line.

[0009] Preferably, the conical cap part is a hollow conical structure, and the bottom of the cone is open to form an inlet groove.

[0010] Preferably, the top end of the conical cap portion gradually transforms into a traction rope portion, and the conical cap portion is a hollow conical structure.

[0011] Preferably, the traction rope portion is a cylindrical strip, and one end of the traction rope portion is a smooth hemispherical shape. The length of the traction rope portion is 55 cm, and the traction rope portion is made of silica gel.

[0012] Preferably, the conical cap portion is made of silica gel. The inner diameter of the bottom of the conical cap portion is 7 mm, and the length of the conical cap portion is 5 cm.

[0013] Preferably, the outer surfaces of the traction rope portion and the conical cap portion are both smooth and elastic.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] Through the two parts of the traction rope portion and the conical cap portion provided in the present utility model, the materials of silica gel or rubber make the guiding strip and the conical cap soft and elastic. Therefore, the inlet groove can adapt to linear cutting staplers of various brand models, and can form a stable connection with cutting staplers of various materials and has a large frictional force, and is not easy to fall off during use. Moreover, it can guide the metal anvil of the linear cutting stapler in the cavity to pass safely and smoothly through the narrow perivascular space, thereby reducing the difficulty of surgical operation, avoiding damage to blood vessels and surrounding tissues. Because it can achieve the effect of successful operation at one time, it can avoid tissue damage and time waste caused by repeated attempts to pass through the perivascular space, so it can avoid accidental bleeding, shorten the operation duration, and reduce the anesthesia time of the patient.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1:

[0020] Please refer to Figure 1 As shown, a guiding strip for a linear cutting stapler in a body cavity includes:

[0021] Traction rope portion 1;

[0022] The conical cap part 2, the top end of the conical cap part 2 gradually transforms into the traction rope part 1. They are made of the same material and are integrally formed without a clear demarcation line. The conical cap part 2 is a hollow conical structure, and the bottom of the cone is open to form an inlet groove 3. The top end of the conical cap part 2 gradually transforms into the traction rope part 1. The conical cap part 2 is a hollow cone structure, the traction rope part 1 is a cylindrical strip, and one end of the traction rope part 1 is a smooth hemispherical shape. The length of the traction rope part 1 is 55 cm, the traction rope part 1 is made of silica gel, the conical cap part 2 is made of silica gel, the inner diameter of the bottom of the conical cap part 2 is 7 mm, and the length of the conical cap part 2 is 5 cm. The outer surfaces of the traction rope part 1 and the conical cap part 2 are both smooth and elastic.

[0023] Specifically, the traction rope part 1 and the conical cap part 2 are made of silica gel as the manufacturing material. This material is soft and not easily cause damage to human tissues even if excessive force is accidentally applied during the operation. The soft material can be bent at will and only needs to be guided by corresponding surgical instruments during the operation to adapt to different angle requirements. The silica gel material can form a stable connection with various types of cutting and suturing devices and has a large frictional force, making it not easy to fall off during use. Moreover, it can guide the metal anvil head of the intracavitary linear cutting and suturing device to pass safely and smoothly through the narrow paravascular space to complete the cutting and closing operation of blood vessels.

[0024] As can be seen from the above, during use, first use surgical instruments to clamp a part of the traction rope part 1, make the head end enter the body cavity, pass through the paravascular space, and use a hemostatic forceps to clamp the head end of the traction rope part 1 that has passed through the paravascular space and pull it out of the body cavity. Then, outside the body cavity, insert the anvil head of the linear cutting and suturing device into the bottom of the hollow cone of the cap part, insert it to an appropriate depth to make the connection firm. Then, pull the traction rope part 1 and smoothly push the linear cutting and suturing device into the body cavity. Along the guidance of the traction rope part 1, extend the anvil head into the paravascular space so that the blood vessel to be transected enters the jaws. Depending on the specific situation, pull the traction rope part 1 to separate the conical cap part 2 from the anvil head of the linear cutting and suturing device, or directly close the jaws of the linear cutting and suturing device to perform the cutting and closing transection operation on the blood vessel.
