Problems solved by technology

Vascular suture anastomosis is a vascular anastomosis method that uses sutures to butt and suture the broken ends of blood vessels. Although it is the "gold" standard of vascular anastomosis, it also has the following defects: 1. The suture causes damage to the intima of the vessel; 2. The suture is exposed to the lumen and interferes with the normal blood flow; 3. The anastomotic stoma is turned inward, etc. , increased risk of vascular embolism
4. The operation is cumbersome and the operation time is long; 5. The doctor's skills are required to be high, and it is difficult to master them proficiently in a short period of time without training
6. The quality of surgery is easily affected by the doctor's psychological and physiological fluctuations; 7. Blood vessels are elastic, soft, and stretchable human tissues, so it is difficult to position them by manual suture, and it is difficult to suture accurately with needles
Although the application of vascular mechanical nail-loop anastomosis obviously simplifies the operation and shortens the operation time, it also has the following disadvantages: figure 1 As shown, the inner diameters of the two plastic rings must be the same, so blood vessels with different diameters cannot be anastomosed
Causes doctors to feel inconvenient and flexible to operate

Embodiment 1

[0081] Please refer to the attached image 3 , image 3 It is an exploded view of the structure of a specific embodiment of the small lumen stapler provided by the present invention, which can conveniently solve the anastomosis problem of small lumens and arterial vessels, and cause less damage to the human body during the anastomosis operation, and promote the small lumen of the human body. The standardization of lumen and arterial anastomosis increases the operation convenience of anastomosis and reduces the difficulty of operation and training time for doctors.

[0082]In the above specific embodiments, the small lumen stapler provided by the present invention is generally in the shape of a long column, and the axial section of the column is similar to a petal shape. A small lumen anastomosis system consists of 4 parts. The four parts are respectively a fixed sleeve 100, a movable sleeve 200, a handle 300, and a lock 400. All 4 parts can be made of non-absorbable or reso...

Embodiment 2

[0111] The structure of the small lumen stapler provided in this embodiment can be summarized as follows: a fixed sleeve, a movable sleeve and a lock; one end of the fixed sleeve is provided with a shoulder; the other end of the fixed sleeve An anastomotic connection end is provided; the movable sleeve is sleeved on the cylinder wall of the fixed sleeve, and a hanging pin is provided at the end away from the cylinder shoulder, and the movable sleeve has a Freedom of movement for sliding in the length direction; the length of the movable sleeve is such that when one end close to the cylinder shoulder fits the cylinder shoulder, the anastomotic connection end is exposed relative to the end surface of the other end of the movable sleeve; The lock buckle is made of elastic material with a ring shape and a locking part. The shape of the inner hole of the lock buckle matches the shape of the anastomotic connection end; the wall of the fixed sleeve faces inward At least one recess is...

Abstract

Disclosed are a small lumen anastomat and a use method therefor, wherein same aim at solving the technical problem of anastomosis of an arterial blood vessel and a human body small lumen. The small lumen anastomat structurally comprises: a fixed sleeve (100), a movable sleeve (200) and a lock catch (400), wherein one end of the fixed sleeve (100) is provided with a sleeve shoulder, and the other end of the fixed sleeve (100) is provided with an anastomosis connecting end; the movable sleeve (200) is sleeved on a sleeve wall of the fixed sleeve (100), and is provided with hanging needles (230, 260), and the movable sleeve (200) has the degree of freedom of movement of sliding in a lengthwise direction of the fixed sleeve (100); the length of the movable sleeve (200) satisfies the condition where when the end of the movable sleeve close to the sleeve shoulder is attached to the sleeve shoulder, the anastomosis connecting end is exposed relative to an end face of the other end of the movable sleeve (200); the lock catch (400) is made of an elastic material, has an annular contour and is provided with a locking part, and the shape of an inner hole of the lock catch (400) matches the contour of the anastomosis connecting end; and a sleeve wall face of the fixed sleeve (100) is provided with at least one recessed portion in an inner cavity direction, and the contour of a sleeve cavity of the movable sleeve (200) matches the contour of an outer wall of the fixed sleeve (100). The device can improve the success rate of a surgery and enable the surgery to be safer.

Description

technical field [0001] The invention relates to the technical field of blood vessel and human small lumen anastomosis, in particular to a small lumen stapler. Background technique [0002] Human lumen anastomosis is a surgical technique that connects two broken lumens of the human body into one. Vascular suture anastomosis is a vascular anastomosis method that uses sutures to butt and suture the broken ends of blood vessels. Although it is the "gold" standard of vascular anastomosis, it also has the following defects: 1. The suture causes damage to the intima of the vessel; 2. The suture is exposed to the lumen and interferes with the normal blood flow; 3. The anastomotic stoma is turned inward, etc. , increasing the risk of vascular embolism. 4. The operation is cumbersome and the operation time is long; 5. The doctor's skill requirements are high, and it is difficult to master it proficiently in a short period of time without training. 6. The quality of the operation is...
