Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of laparoscopic surgery, and particularly to a tissue extraction assembly. Background Art
[0002] Minimally invasive surgery, as the name implies, is a surgery with minimal trauma. It refers to surgeries performed using modern medical devices and related equipment such as laparoscopes and thoracoscopes. In minimally invasive surgery, tissue resection and other surgeries are performed by passing medical devices through Trocar holes made in the patient's abdominal wall.
[0003] Taking laparoscopic cholecystectomy as an example, after the gallbladder is removed, the gallbladder is placed in a specimen bag, and then the specimen bag is pulled out / pushed out through the Trocar hole. However, since the posture of the gallbladder in the specimen bag is not fixed, that is, the bottom of the gallbladder may face the mouth of the specimen bag, or the gallbladder may be placed horizontally in the specimen bag, and the most ideal posture is that the cystic duct faces the mouth of the specimen bag. Because when the gallbladder is placed horizontally or the bottom of the gallbladder faces outward below the Trocar hole, it is very difficult for medical staff to remove the gallbladder from the Trocar hole with a diameter of no more than 1 cm without using special tools. At this time, if medical staff take measures such as enlarging the incision or pulling forcefully to see the gallbladder, it does not conform to the principle of minimally invasive surgery. Secondly, pulling forcefully may cause the specimen bag to rupture, and the bile in the gallbladder flows into the abdominal cavity, causing pollution to the abdominal cavity and even leading to serious consequences such as tumor spread and metastasis. Summary of the Invention
[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present disclosure is to provide a tissue extraction assembly to solve the problems in the related art.

[0028] Figure 1 Shown is a schematic diagram of the overall structure of the tissue extraction assembly in the embodiment of the present disclosure. Figure 2 Shown is a schematic diagram of the overall structure of another state of the tissue extraction assembly in the embodiment of the present disclosure. Figure 3 Shown is a cross-sectional structure schematic diagram of the bag body 10 in the embodiment of the present disclosure. In Figure 1 、 Figure 2 and Figure 3In the example, the tissue extraction component includes a bag body 10, a buckle 20, and a first drawstring 30. The bag body 10 includes a bag mouth 101 and a receiving cavity 102. The receiving cavity 102 communicates with the bag mouth 101. One end of the first drawstring 30 is connected to the buckle 20, and the other end is connected to the bag mouth 101 of the bag body 10. Exemplarily, the bag body 10 is made of a skin-friendly material to avoid discomfort inside the patient's abdominal cavity due to material reasons. Exemplarily, the bag body 10 is made of an elastic material to improve the receiving cavity for the excised tissue and enhance the applicability of receiving the tissue.
[0029] In Figure 1 and Figure 2 the example, the buckle 20 has a fixed arm 21 and a clamping arm 22. One end of the clamping arm 22 is fixedly arranged at one end of the fixed arm 21. Exemplarily, the buckle 20 has elasticity. When the clamping arm 22 swings away from the fixed arm 21, the fixed arm 21 has an opening 2101. When the clamping arm 22 restores its elasticity and gradually approaches the fixed arm 21, it blocks the opening 2101, and a clamping space 201 is formed between the clamping arm 22 and the fixed arm 21. For example, the buckle 20 is implemented as a hemolock clip. During use, a specific surgical forceps is used to swing the clamping arm 22 away from the fixed arm 21 to expose the opening 2101 of the fixed arm 21. After placing the tissue (such as the cystic duct) in the clamping space 201, the clamping arm 22 can be reset. At this time, the clamping arm 22 tightly clamps the cystic duct due to its own elasticity.
[0030] In Figure 1 and Figure 2 the example, a plurality of spaced-apart clamping teeth 23 are formed on the inner side wall of the buckle 20. That is, a plurality of spaced-apart clamping teeth 23 are formed on the inner wall of the buckle 20 that encloses the clamping space 201. And the plurality of clamping teeth 23 are distributed in a staggered manner in opposite rows. In this way, the plurality of clamping teeth 23 in two upper and lower rows and distributed in a staggered manner can improve the clamping force of the buckle 20 on the cystic duct located in the clamping space 201 to prevent the cystic duct from falling out of the clamping space 201 during subsequent operations. Exemplarily, the clamping teeth 23 have elasticity to prevent the clamping force of the clamping teeth 23 from being too large and causing damage to the cystic duct to ensure the integrity of the cystic duct.
[0031] In Figure 1 and Figure 2In the example, the size of the buckle 20 is smaller than the size of the bag opening 101, so that the buckle 20 can smoothly enter and exit the bag opening 101. Exemplarily, the corners of the bag body 10 are rounded to reduce the damage caused by the bag body 10 to the patient's body when the bag body 10 moves in the patient's body.
[0032] Figure 4 FIG. 1 is a schematic diagram of the structure of the gallbladder tube located at the bottom end of the accommodating cavity in an embodiment of the present disclosure. Figure 5 The structure diagram of the gallbladder tube located at the bag opening in the embodiment of the present disclosure is shown in FIG. Figure 2 , Figure 4 and Figure 5 As can be seen from the example, during operation, the medical staff places the bag body 10 into the patient's body through the Trocar hole, operates the clamping arm 22 with surgical forceps (clip applicator), makes the opening 2101 of the buckle 20 in the patient's body open, places the cystic duct of the removed gallbladder in the clamping space 201, and after abutting the clamping teeth 23 on the fixing arm 21, restores the clamping arm 22 to the original state to close the opening 2101, so that the clamping teeth 23 on the holding arm 22 abut the cystic duct, thereby clamping the cystic duct in the clamping space 201. Then, the gallbladder and the buckle 20 are placed in the accommodating cavity 102 through the bag opening 101.
[0033] When the gallbladder duct in the bag body 10 is in Figure 4 In the state in the example, and when the gallbladder needs to be removed from the patient's body, the medical staff first pulls the bag opening 101 of the bag body 10 to the outside of the Trocar hole, and then pulls the buckle 20 by pulling the first pull rope 30, and the buckle 20 drives the cystic duct to be pulled toward the bag opening 101, so that the buckle 20 no longer clamps the gallbladder, and then the liquid in the gallbladder is discharged to the outside of the body. At this time, the bag body 10 can be directly removed from the patient's body due to the reduction in the volume of the gallbladder. Through the tissue removal component in the embodiment of the present disclosure, the damage to the patient caused by the auxiliary tool reaching into the bag body 10 to clamp and pull the gallbladder duct to the outside of the Trocar hole according to the traditional method is avoided, and the effect and efficiency of pulling the gallbladder duct to the bag opening 101 can be improved. Exemplarily, the first pull rope 30 is made of skin-friendly material to avoid discomfort caused by material reasons inside the patient's abdominal cavity.
[0034] exist Figure 1 , Figure 2 , Figure 4 and Figure 5In the example, the tissue extraction assembly further includes a second drawstring 40, which is connected to the bag opening 101 of the bag body 10. When extracting tissue from a patient's body, the free end of the second drawstring 40 is located outside the patient's body, so that medical staff can pull the bag opening 101 of the bag body 10 to the Trocar hole by pulling the free end of the second drawstring 40, further avoiding the harm caused to the patient when using auxiliary tools to reach into the patient's body to clamp and pull the bile duct to outside the Trocar hole. Exemplarily, the second drawstring 40 is made of skin-friendly material to avoid discomfort inside the patient's abdominal cavity due to the material reason.
[0035] In another embodiment, the tissue may also be other organs of the human body.
[0036] In summary, the tissue extraction assembly provided in the embodiments of the present disclosure includes a bag body having a bag opening and a receiving cavity, the bag opening communicating with the receiving cavity; an openable and closable buckle for clamping tissue; a first drawstring, one end of which is connected to the buckle and the other end is connected to the bag body. Through the tissue extraction assembly in the embodiments of the present disclosure, the harm caused to the patient by using auxiliary tools to reach into the bag body to clamp and pull the excised tissue according to the traditional method is avoided, and at the same time, the effect and efficiency of pulling the excised tissue to the bag opening can be improved.
