Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a single-hole multi-channel laparoscope puncture device. BACKGROUND

[0002] With the progress of medical technology and the improvement of medical equipment, people have higher and higher requirements for minimally invasive and non-invasive. In order to meet the pursuit of patients, single-hole laparoscopic surgery is thus produced. Early non-invasive laparoscopic surgery is mostly performed through natural cavities such as esophagus, trachea, vagina, rectum and other natural holes of human body to achieve the effect of "non-invasive". However, directly entering the abdominal cavity through the natural cavity for surgery is easy to cause postoperative perforation, infection and other complications, which limits its development trend. In 1969, Wheelsps first reported that a young woman underwent trans-umbilical single-hole tubal ligation surgery using the natural "scar" navel of the human body as an incision, and the appearance of the incision after the surgery was close to "non-invasive". Later, single-hole laparoscopic surgery has been widely used and developed in adult surgery, especially in gynecology and urology.

[0003] In the related art, a single-hole multi-channel laparoscope device is disclosed in Chinese Patent No. CN202320199095.9, which includes a guide cover arranged outside the body wound of a machine body and used for guiding instruments. The cover body of the guide cover is in a curved surface structure with an oval bottom surface. A plurality of operation holes for inserting surgical instruments are arranged in a linear arrangement at the top of the cover body. The projection of the center of the operation hole on the bottom surface of the cover body is on the long axis of the oval. A guide tube integrally connected to the cover body of the guide cover is arranged at the operation hole. A gas-tight member is arranged in the free end of the guide tube. An air inlet pipe and an air outlet pipe can also be arranged on the cover body.

[0004] In the related art, the height of the air inlet pipe and the air outlet pipe extending into the cover body is the same, so that the air outlet pipe often discharges clean gas just discharged from the air inlet pipe instead of smoke generated during the operation. When the smoke cannot be discharged from the cover body in time, the doctor cannot clearly observe the situation inside the wound of the patient through the operation hole on the cover body, thereby affecting the progress of the operation. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the problem that the height of the air inlet pipe and the air outlet pipe extending into the cover body is the same, so that the smoke cannot be discharged from the cover body in time, thereby affecting the progress of the operation, the present application provides a single-hole multi-channel laparoscope puncture device.

[0006] The single-hole multi-channel laparoscope puncture device provided by the present application adopts the following technical scheme:

[0007] A single-hole multi-channel laparoscope puncture device, comprising

[0008] The guide cover is provided with a plurality of operation pipes at one end and a cut protection sleeve at the other end for embedding into the abdominal cavity;

[0009] The air inlet pipe is arranged in the guide cover and extends into the cut protection sleeve;

[0010] The air outlet pipe is arranged in the guide cover and above the cut protection sleeve.

[0011] Further, the air inlet pipe has a smaller diameter than the air outlet pipe.

[0012] Further, the air inlet pipe and the air outlet pipe are provided with a plurality of side holes.

[0013] Further, the air inlet pipe is made of flexible material.

[0014] Further, the air inlet pipe and the air outlet pipe are provided with valves.

[0015] Further, the operation pipes are detachably provided with trocars.

[0016] Further, the operation pipes are arranged along the circumferential edge of the guide cover.

[0017] Further, the guide cover is provided with a flexible ring at the end close to the cut protection sleeve, and the end of the cut protection sleeve is arranged in the flexible ring.

[0018] In summary, the present application has at least one of the following beneficial technical effects:

[0019] 1. The bottom end of the air inlet pipe is arranged in the guide cover and extends into the cut protection sleeve, so that the air inlet pipe can quickly introduce clean and safe gas into the abdominal cavity of the patient, so that the smoke generated by the surgical incision in the abdominal cavity of the patient is quickly diluted, and then the smoke in the abdominal cavity of the patient is quickly discharged into the guide cover and discharged through the air outlet pipe in the guide cover, so that the doctor can quickly and clearly view the surgical progress in the abdominal cavity of the patient, and improve the efficiency and quality of the operation;

[0020] 2. The air inlet pipe and the air outlet pipe are provided with a plurality of side holes, and the side holes are arranged in the guide cover. When the clean and safe gas is introduced into the guide cover through the air inlet pipe, part of the gas will overflow from the side holes of the air inlet pipe and dilute the smoke above the bottom end of the air outlet pipe in the guide cover, so that the smoke above the bottom end of the air outlet pipe in the guide cover is quickly discharged through the side holes of the air outlet pipe, ensuring that the doctor can quickly and clearly view the surgical progress in the abdominal cavity of the patient, and improve the efficiency and quality of the operation;

[0021] 3. The diameter of the gas inlet tube is smaller than that of the gas outlet tube, so that the clean and safe gas can enter into the patient's abdominal cavity at a faster flow rate through the small-diameter gas inlet tube, thereby accelerating the flow of smoke in the patient's abdominal cavity, so that the smoke in the patient's abdominal cavity can be quickly discharged into the guide cover and discharged through the large-diameter gas outlet tube.

[0026] In order to make the objects, technical solutions and advantages of the present application more clear, the technical solutions in the present application will be clearly and completely described below in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] The embodiment of the present application discloses a single-hole multi-channel laparoscope puncture device. Referring to Figure 1 and Figure 2 A single-hole multi-channel laparoscope puncture device includes a guide cover 1, a gas inlet tube 4 and a gas outlet tube 5. One end of the guide cover 1 is closed and the other end is open. The open end of the guide cover 1 is connected with an incision protection sleeve 3. The end of the incision protection sleeve 3 away from the guide cover 1 can be inserted into the patient's abdominal cavity, so that the guide cover 1 is connected with the patient's abdominal cavity through the incision protection sleeve 3. A plurality of operation conduits 2 are arranged on the closed end of the guide cover 1. Surgical instruments can be inserted into the guide cover 1 through the operation conduits 2, thereby realizing surgical operation on the patient's abdominal cavity.

[0028] Considering that a laser knife is often used to cut tissues when operating on a patient's abdominal cavity, some smoke is generated when the laser knife is inserted into the guide cover 1 through the operation conduit 2 and enters the patient's abdominal cavity to cut tissues, and the smoke is dispersed in the guide cover 1 and the patient's abdominal cavity, making it difficult for the doctor to clearly view the operation progress in the patient's abdominal cavity. Therefore, referring to Figure 1 and Figure 2 , the air inlet pipe 4 and the air outlet pipe 5 are both communicated and mounted on the closed end of the guide cover 1, when a large amount of smoke is dispersed in the guide cover 1 and the patient's abdominal cavity, clean and safe gas can be injected into the guide cover 1 through the air inlet pipe 4, so that the gas can discharge the smoke in the guide cover 1 and the patient's abdominal cavity from the air outlet pipe 5, thereby reducing the concentration of smoke in the guide cover 1 and the patient's abdominal cavity, so that the doctor can clearly view the operation progress in the patient's abdominal cavity through the operation conduit 2 on the guide cover 1.

[0029] In order to improve the efficiency of discharging smoke from the guide cover 1, referring to Figure 1 and Figure 2 , the length of the air inlet pipe 4 inserted into the guide cover 1 is greater than the length of the air outlet pipe inserted into the guide cover 1, in the embodiment, the bottom end of the air inlet pipe 4 penetrates the guide cover 1 and extends into the incision protection sleeve 3, so that the air inlet pipe 4 can quickly guide clean and safe gas into the patient's abdominal cavity, so as to quickly dilute the smoke generated by the surgical incision in the patient's abdominal cavity, and then the smoke in the patient's abdominal cavity is quickly discharged from the abdominal cavity into the guide cover 1. In order to avoid damage to the tissues in the patient's abdominal cavity caused by the air inlet pipe 4, the air inlet pipe 4 is made of flexible material, such as rubber material. The bottom end of the air outlet pipe 5 is communicated and inserted into the guide cover 1 and located above the incision protection sleeve 3, so that the smoke discharged from the abdominal cavity can be quickly discharged through the air outlet pipe 5.

[0030] In order to further improve the efficiency of discharging smoke from the guide cover 1, referring to Figure 1 and Figure 2 , the diameter of the air inlet pipe 4 is smaller than the diameter of the air outlet pipe 5, so that the clean and safe gas can enter the patient's abdominal cavity at a faster flow rate through the small-diameter air inlet pipe 4, thereby accelerating the flow of smoke in the patient's abdominal cavity, so that the smoke in the patient's abdominal cavity can be quickly discharged into the guide cover 1 and discharged through the large-diameter air outlet pipe 5.

[0031] Considering that there is smoke dispersed in the patient's abdominal cavity and the guide cover 1, and the smoke above the bottom end of the air outlet pipe 5 in the guide cover 1 is difficult to be quickly discharged, therefore, referring to Figure 1 and Figure 2The side wall of the air inlet pipe 4 and the air outlet pipe 5 is provided with a plurality of side holes 6, and the side holes 6 are located in the guide cover 1. When the clean and safe gas is flushed into the guide cover 1 through the air inlet pipe 4, part of the gas will overflow from the side holes 6 of the air inlet pipe 4 and dilute the smoke above the bottom end of the air outlet pipe 5 in the guide cover 1, so that the smoke above the bottom end of the air outlet pipe 5 in the guide cover 1 is quickly discharged through the side holes 6 of the air outlet pipe 5.

[0032] During the operation process, when the smoke needs to be discharged, the patient's abdominal cavity needs to be raised to facilitate the operation of the patient's abdominal cavity, so with reference to Figure 1 and Figure 2 The air inlet pipe 4 and the air outlet pipe 5 are provided with valves 7, and the valves 7 are located outside the guide cover 1. The valves 7 can control the opening and closing of the air inlet pipe 4 and the air outlet pipe 5. When the patient's abdominal cavity needs to be raised, the valve 7 on the air outlet pipe 5 can be closed, the valve 7 on the air inlet pipe 4 can be opened, and the clean and safe gas can be injected into the patient's abdominal cavity through the air inlet pipe 4, so that the patient's abdominal cavity is raised, thereby facilitating the operation. When the smoke generated during the operation process needs to be discharged, the valves 7 on the air inlet pipe 4 and the air outlet pipe 5 can be opened, and the clean and safe gas can be introduced into the patient's abdominal cavity through the air inlet pipe 4, so that the smoke in the patient's abdominal cavity and the guide cover 1 is diluted, and the smoke is discharged from the air outlet pipe 5, ensuring that the doctor can clearly view the operation process in the patient's abdominal cavity through the operation pipe 2 on the guide cover 1.

[0033] With reference to Figure 1 and Figure 2 In the embodiment of the present application, four operation pipes 2 are provided, and the four operation pipes 2 are arranged along the circumferential edge of the guide cover 1. The heights of the adjacent two operation pipes 2 extending out of the guide cover 1 are different, and the heights of the two operation pipes 2 located on the same diagonal line extending out of the guide cover 1 are the same, so that the surgical instruments inserted into the guide cover 1 through the corresponding operation pipes 2 for surgical operation are not easy to collide with each other. The end of the operation pipe 2 located outside the guide cover 1 is detachably provided with a trocar 8. The connection mode between the trocar 8 and the end of the operation pipe 2 can be clamping or threaded connection, so that the appropriate trocar 8 can be selected and installed according to the size of the required surgical instrument, so that the surgical instrument can be stably inserted into the operation pipe 2 through the trocar 8 for surgical operation.

[0034] It is considered that the laparoscope device needs to be used for laparoscopic treatment of children, and the skin of children is tender, and the umbilical incision of children is generally 2 cm. Therefore, with reference to Figure 1 and Figure 2The inner wall of the open end of the guide cover 1 is provided with a clamping groove 11, the one end of the incision protection sleeve 3 is provided with a clamping ring 10 matched with the clamping groove 11, and the other end is provided with a flexible clamping ring 12. Different sizes of incision protection sleeves 3 can be selected according to the patient's condition to connect with the guide cover 1. When the child needs to be operated on the abdominal cavity, the incision protection sleeve 3 with a 4cm flexible clamping ring 12 can be selected, and the clamping ring 10 is clamped in the clamping groove 11 on the guide cover 1, so that the laparoscope device can be used for the child's abdominal cavity surgery treatment. The one end of the guide cover 1 close to the incision protection sleeve 3 is provided with a flexible clamping ring 9 made of rubber or silicone. The outer part of the flexible clamping ring 9 is trumpet-shaped, and the inner part is straight cylindrical. The small end of the flexible clamping ring 9 is connected with the guide cover 1, and the one end of the incision protection sleeve 3 is located in the flexible clamping ring 9. When the one end of the incision protection sleeve 3 away from the guide cover 1 is inserted into the patient's abdominal cavity, the flexible clamping ring 9 is elastically abutted on the outer wall of the patient's abdomen, and the flexible clamping ring 9 can make the guide cover 1 be stably abutted on the outer wall of the patient's abdomen, and also avoid the guide cover 1 to press the patient's abdomen.

[0035] The implementation principle of the single-hole multi-channel laparoscope puncture device is as follows: according to the patient's condition, the appropriate size of the incision protection sleeve 3 and the trocar 8 are selected, so that the clamping ring 10 of the incision protection sleeve 3 is clamped and fixed in the clamping groove 11 of the open end of the guide cover 1, and the trocar 8 is sleeved and installed on the one end of the operation pipeline 2 located outside the guide cover 1. Then the flexible clamping ring 12 on the incision protection sleeve 3 is inserted from the incision of the patient's abdomen. At this time, the guide cover 1 is communicated with the patient's abdominal cavity through the incision protection sleeve 3, and the flexible clamping ring 9 is stably abutted on the outer wall of the patient's abdomen. Then the surgical instrument is inserted into the guide cover 1 through the corresponding operation pipeline 2, the valve 7 on the exhaust pipe 5 is closed, the valve 7 on the air inlet pipe 4 is opened, and clean and safe gas is injected into the patient's abdominal cavity through the air inlet pipe 4, so that the patient's abdominal cavity is bulged, thereby facilitating the development of the operation. Finally, when the smoke generated during the operation needs to be discharged, the valves 7 on the air inlet pipe 4 and the exhaust pipe 5 are opened, clean and safe gas is introduced into the patient's abdominal cavity through the air inlet pipe 4, so that the smoke in the patient's abdominal cavity and the guide cover 1 is diluted, and the smoke is discharged from the exhaust pipe 5, ensuring that the doctor can clearly view the operation process in the patient's abdominal cavity through the operation pipeline 2 on the guide cover 1.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features. The modification or replacement does not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
