Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a disposable laparoscopic soft instrument sheath. Background Art

[0002] During clinical minimally invasive abdominal surgery, instruments such as laparoscopes, forceps, and scissors need to be inserted into the patient's body for surgical operations. During the operation, a low level of compressed air is added to the patient's abdominal cavity and maintained to ensure that the surgical operation space is sufficient and convenient for operation.

[0003] Existing laparoscopic surgical instruments are mainly composed of a sleeve, a main body, an inflation valve, and an incision expander, wherein the sleeve, the main body, and the inflation valve are connected as a whole, and the incision expander is an independent accessory with a fixing ring on it. When in use, the fixing ring must be peeled off from the incision expander first, and the other end of the incision expander is placed into the incision of the patient's abdominal cavity. The outer ring of the incision expander is flipped to allow the soft sleeve of the incision expander to gradually expand and expand the incision, and then the fixing ring is installed on the outer ring of the incision expander. Then, the buckle seat on the main body is installed into the fixing ring of the incision expander, and the main body and the incision expander are firmly locked and connected with a connecting buckle piece to perform related surgical operations. Existing laparoscopic surgical instruments have the following disadvantages: 1. The sleeve is prone to air leakage and has a fixed size. One type of sleeve can only correspond to the size of surgical instruments; 2. The structure is complex and the operation is cumbersome. When using, the fixing ring must be peeled off from the incision expander first, and then the wound is expanded. After the wound is expanded, the fixing ring must be installed into the incision expander again. Finally, the main body must be installed into the incision expander and firmly locked with a connecting buckle before the operation can be performed; 3. The product has multiple joints and is very prone to air leakage during use, resulting in the inability to perform the operation normally; 4. The exhaust valve is a three-way structure, which requires both hands to operate, which is inconvenient. Summary of the invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a disposable laparoscopic soft instrument sheath, which reduces leakage points by arranging a sleeve, a main body, an inflation valve, and an incision expander as an integral structure, avoids air leakage during surgery that may cause interruption of the surgery, and improves the efficiency and quality of the surgery.

[0005] The present invention provides a disposable laparoscopic soft instrument sheath, comprising a main body, a sleeve, a sealing cap, an air inlet and outlet module, an incision expander, a flat ring and an inner ring. The main body is composed of a truncated cone and a cylinder vertically arranged along the central axis from top to bottom. Four connecting holes, an exhaust hole and an inflation hole are evenly arranged on the upper surface of the main body. The connecting holes are arranged in a circle. The exhaust hole and the inflation hole are respectively located on the left and right sides of the connecting hole. A sleeve is installed in the connecting hole. A sealing cap is installed on the top of the sleeve. An instrument inlet hole is arranged at the center of the sealing cap. The instrument inlet hole is used for the entry of surgical instruments. The air inlet and outlet module is arranged on the top of the main body. The air inlet and outlet module is used for exhausting or supplying gas to the human body. The incision expander is vertically connected to the bottom of the main body. The incision expander is a transparent soft cover structure and the soft cover structure is double-layered. The inner ring is arranged on the inner layer of the bottom of the incision expander. The flat ring is sleeved on the incision expander, and the incision expander is located above the inner ring.

[0006] Furthermore, the intake and exhaust module includes a smoke exhaust pipe, a smoke exhaust valve, an air charging pipe and an air charging valve. The smoke exhaust pipe is connected to the exhaust hole, and the smoke exhaust valve is installed on the smoke exhaust pipe; the air charging pipe is installed on the air charging hole, and the air charging valve is installed on the air charging pipe. The smoke exhaust pipe is used to discharge smoke inside the abdominal cavity; the smoke exhaust valve is used to control the smoke exhaust process of the smoke exhaust pipe; the air charging pipe is used to inflate the abdominal cavity, and the air charging valve is used to control the air charging process of the air charging pipe.

[0007] Furthermore, the smoke exhaust valve is a one-way valve structure. Such a setting better meets the clinical requirement of one-handed smoke exhaust. When performing surgery, the smoke exhaust valve is adjusted by one hand. Since it is a one-way valve structure, there are only two results of adjustment, either inflation or smoke exhaust, which is very convenient for operation during surgery.

[0008] Furthermore, the inflation valve is provided with a three-way connection, which facilitates the discharge of more smoke generated during the operation to the outside of the body, thereby improving the smoke exhaust efficiency.

[0009] Furthermore, the three-way connection is a one-way valve structure. When smoke exhaust is required during surgery, the surgeon can hold the surgical instrument with one hand and operate the smoke exhaust valve with the other hand, which greatly improves clinical operability and convenience.

[0010] Furthermore, the inner ring is connected to the pull ring through a connecting belt. The setting of the pull ring and the connecting belt facilitates the adjustment of the position of the inner ring. When the pull ring is pulled, the pull ring drives the connecting belt, and the connecting belt drives the inner ring to move, so as to adjust the position of the inner ring.

[0011] Furthermore, the sealing cap is a soft silicone cap, which is a hollow structure. When instruments of different sizes are inserted, the silicone cap can move and deform, which is beneficial for the insertion of the instruments.

[0012] Furthermore, pits are arranged on the top of the soft silicone cap, and the pits are used to reduce the friction resistance between the instrument and the silicone cap.

[0013] The advantages of a disposable laparoscopic soft instrument sheath provided by the present invention are as follows: a disposable laparoscopic soft instrument sheath provided in the structure of the present invention, by arranging a sleeve, a main body, an inflation valve, and an incision expander as an integral structure, is simpler and more convenient to operate, reduces leakage points, and avoids leakage during surgery that causes interruption of the operation; by arranging a sealing cap with a brand-new structure, it can be simultaneously applicable to the operation and application of surgical instruments of various specifications and sizes, while greatly facilitating clinical operation and use, it can ensure an ideal sealing effect; the smoke exhaust valve with a one-way valve structure better meets the clinical one-handed smoke exhaust requirements.

The connecting holes 101 are arranged in a circle, and the exhaust holes 102 and the inflation holes 103 are respectively located on the left and right sides of the connecting hole 101. The sleeve 200 is installed in the connecting hole 101. A sealing cap 300 is installed on the top of 200, and an instrument entry hole 301 is opened at the center of the sealing cap 300, and the instrument entry hole 301 is used for the entry of surgical instruments; the air intake and exhaust module 400 is arranged on the top of the main body 100, and the air intake and exhaust module 400 is used to exhaust or supply gas to the human body; the incision spreader 500 is vertically connected to the bottom of the main body 100, the incision spreader 500 is a transparent soft cover structure and the soft cover structure is double-layered, and an inner ring 700 is arranged on the inner layer of the bottom of the incision spreader 500; the flat ring 600 is sleeved on the incision spreader 500, and the incision spreader 500 is located above the inner ring 700. When in use, first put the flat ring 600 on the outer periphery of the incision spreader 500 and move the flat ring 600 to the middle part of the soft sleeve, then hold the inner ring 700 of the inner layer at the bottom of the spreader and turn the inside of the incision spreader 500 out so that the inner wall of the incision spreader 500 faces outward, and straighten the incision spreader 500. At this time, the flat ring 600 is located above the inner ring 700. Pull the flat ring 600 toward the sleeve 200 and straighten it so that the inner ring 700 is at the front end of the incision spreader 500. After arranging the incision spreader 500 to make it flat, pinch the front After the inner ring 700 at the end is deformed and the pull ring 900 on the inner ring 700 is ensured to be outside the incision expander 500, the incision expander 500 is placed into the patient's surgical incision to the inner wall of the abdominal cavity, and the flat ring 600 on the incision expander 500 is turned over to allow the soft sleeve to gradually expand and fit and seal with the incision, and then the surgical operation can be performed, and the surgical instruments are inserted from the instrument entry hole 301 at the center of the sealing cap 300. Since the sealing cap 300 is made of a soft material and can be deformed, surgical instruments of different specifications can be inserted, and the operation is performed in the abdominal cavity after the surgical instruments are inserted.

[0019] Reference Figure 1The intake and exhaust module 400 includes a smoke exhaust pipe 401, a smoke exhaust valve 402, an air charging pipe 403 and an air charging valve 404. The smoke exhaust pipe 401 is connected to the exhaust hole 102, and the smoke exhaust valve 402 is installed on the smoke exhaust pipe 401; the air charging pipe 403 is installed on the air charging hole 103, and the air charging valve 404 is installed on the air charging pipe 403. The smoke exhaust pipe 401 is used to discharge smoke inside the abdominal cavity; the smoke exhaust valve 402 is used to control the smoke exhaust process of the smoke exhaust pipe 401; the air charging pipe 403 is used to inflate the abdominal cavity, and the air charging valve 404 is used to control the air charging process of the air charging pipe 403. During abdominal examination, the smoke exhaust valve 402 is first opened to allow the smoke inside the abdominal cavity to be discharged through the smoke exhaust pipe 401, and then the inflation valve 404 is opened to pump air into the abdominal cavity through the inflation tube 403 to expand the abdominal cavity, and then the laparoscope, forceps, scissors and other instruments are sent into the patient's body for surgical operation.

[0020] The smoke exhaust valve 402 is a one-way valve structure. Such a setting better meets the clinical requirement of one-handed smoke exhaust. When performing surgery, the smoke exhaust valve 402 can be adjusted by one hand. Since it is a one-way valve structure, there are only two results of adjustment, either inflation or smoke exhaust, which is very convenient for operation during surgery.

[0021] The inflation valve 404 is provided with a three-way connection. The three-way connection is provided to facilitate the discharge of more smoke generated during the operation to the outside of the body, thereby improving the smoke exhaust efficiency.

[0022] The three-way valve is a one-way valve structure. When smoke exhaust is required during surgery, the surgeon can hold the surgical instrument with one hand and operate the smoke exhaust valve 402 with the other hand, which greatly improves clinical operability and convenience.

[0023] Reference Figure 1 The inner ring 700 is connected to the pull ring 900 through the connecting belt 800. The setting of the pull ring 900 and the connecting belt 800 facilitates the adjustment of the position of the inner ring 700. When the pull ring 900 is pulled, the pull ring 900 drives the connecting belt 800, and the connecting belt 800 drives the inner ring 700 to move, so as to adjust the position of the inner ring 700.

[0024] The sealing cap 300 is a soft silicone cap with a hollow structure. When instruments of different sizes are inserted, the cap can move and deform, which is beneficial for the insertion of the instruments.

[0025] The top of the soft silicone cap is provided with pits, and the function of the pits is to reduce the friction resistance between the instrument and the silicone cap.

[0026] Working process: first, put the flat ring 600 on the outer periphery of the incision spreader 500 and move the flat ring 600 to the middle part of the soft sleeve, then hold the inner ring 700 of the inner layer at the bottom of the spreader and turn the inside of the incision spreader 500 out, so that the inner wall of the incision spreader 500 faces outward, straighten the incision spreader 500, at this time, the flat ring 600 is located above the inner ring 700, pull the flat ring 600 towards the sleeve 200 to straighten it, pull the pull ring 900, the pull ring 900 drives the connecting belt 800, and the connecting belt 800 is connected to the sleeve 200. The inner ring 700 is moved and adjusted to be at the front end of the incision expander 500. After the incision expander 500 is arranged to be flat, the inner ring 700 at the front end is pinched to deform it and ensure that the pull ring 900 on the inner ring 700 is outside the incision expander 500. Then, the incision expander 500 is placed into the patient's surgical incision to the inner wall of the abdominal cavity, and the flat ring 600 on the incision expander 500 is turned over to allow the incision expander 500 to gradually expand and fit and seal with the surgical incision.
