Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a balloon structure and uterine lifting forceps for hysterectomy surgery. Background Art

[0002] In gynecological surgery, especially laparoscopic hysterectomy, it is crucial to maintain intra-abdominal air pressure. Traditionally, CO2 gas is used to fill the abdominal cavity to facilitate surgical operations. However, during surgery, especially when the vaginal vault is cut, the abdominal cavity is connected to the vagina, resulting in gas leakage, which affects the abdominal air pressure and the efficiency of surgical operations. Current solutions, such as using salt gauze to pack the vaginal opening, reduce gas leakage to a certain extent, but still have the problem of poor airtightness.

[0003] To address this problem, there are a variety of utility model patents for uterine manipulators, including inflatable uterine manipulators and uterine lifting cups, etc. These devices are designed to assist laparoscopic operations by adjusting the angle and direction of the uterus, but their structures are relatively complex and require high operating skills from the doctor.

[0004] In order to improve the airtightness and ease of operation during surgery, a new type of airbag structure and uterine lifting forceps are needed. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a balloon structure and a uterine lifting forceps for hysterectomy surgery. The uterine lifting forceps with the balloon structure can prevent gas leakage even when the vaginal vault is incised, and can effectively maintain the air pressure in the abdominal cavity, thereby improving the efficiency and safety of the surgical operation.

The first forceps body and the second forceps body both include forceps arms and gripping handles. The head of the forceps arm of the first forceps body is in an arc shape, and the head of the forceps arm of the second forceps body is in a hook shape, and the forceps arm of the first forceps body is longer than the forceps arm of the second forceps body.

[0011] Preferably, the support portion of the balloon structure is provided with a mounting channel with a rectangular cross section, the mounting channel is adapted to the cross-sectional outer contour of the hinge between the first clamp body and the second clamp body, and the length of the rectangular cross section of the mounting channel gradually increases from the middle to both ends.

[0012] Preferably, the support portion has one end close to the first capsule with two sleeves symmetrically arranged in the upper and lower parts, one end of the two sleeves is connected to the installation channel, and the other end is provided with a narrowing ring, and both clamp arms are provided with an annular positioning groove adapted to the narrowing ring.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0026] See also Figure 1 - Figure 6 In this embodiment, a balloon structure 1 and a uterine lifting forceps 2 for hysterectomy are provided, which are specifically used to prevent gas leakage in the abdominal cavity caused by the incision of the vaginal vault during hysterectomy under laparoscopy. The structure specifically comprises: a support part 11 and an airbag part 12. The inner wall of the support part 11 is provided with an air supply tube 111, and the airbag part 12 is sleeved on the outer side of the support part 11, and the air supply tube 111 is communicated with the airbag part 12.

[0027] Specifically, in this embodiment, when the doctor is performing a laparoscopic hysterectomy, the balloon structure 1 can be folded up when not in use, and can be placed on the uterine lifting forceps 2 through the support part 11 when needed. By filling the gas into the air pipe 111 of the support part 11 of the balloon structure 1 (specifically, by connecting the injection port of the syringe to one end of the hose, one end of the hose to the air pipe 111, pushing the syringe piston to inflate the air bag part 12, and pulling the syringe piston to deflate the air bag part 12), the air bag part 12 located outside the support part 11 expands and tightly clamps the vagina, thereby preventing the gas in the abdominal cavity from escaping from the vagina due to the incision of the vaginal vault during laparoscopic hysterectomy. This design simplifies the operation process and improves air tightness, and is expected to become an important auxiliary tool in laparoscopic hysterectomy.

[0028] See also Figure 1 - Figure 3 The airbag portion 12 adopts a double spherical balloon structure, which includes a first balloon 121 and a second balloon 122. The support portion 11 is provided with a first catheter 14 and a second catheter 15 which are respectively communicated with the first balloon 121 and the second balloon 122. The first catheter 14 is connected to the air delivery pipe 111 of the first balloon 121, and the second catheter 15 is connected to the air delivery pipe 111 of the first balloon 121. Gas is introduced into the first catheter 14 and the second catheter 15 to inflate the first balloon 121 and the second balloon 122, respectively acting on the front and rear parts of the inner wall of the vagina, so that the airbag portion 12 fits the two parts, so that a first closed cavity is formed between the abdominal cavity, the inner wall of the vagina, and the first balloon 121, and a second annular closed cavity is formed between the first balloon 121, the second balloon 122, and the inner wall of the vagina, which has a double sealing effect. Since there are wrinkles in the vagina, a double spherical capsule structure is used, so that the first capsule 121 and the second capsule 122 clamp the wrinkles of the vaginal inner wall after expansion, so as to achieve better fixation of the balloon structure 1. On the basis of the first capsule 121 and the second capsule 122 being fitted with the vaginal inner wall, the possibility of the airbag moving and slipping during the operation can be effectively reduced. In addition, in the case of a long operation time, the first and second capsules 121 and 122 can be expanded separately through the first catheter 14 and the second catheter 15, and the expansion state of the first and second capsules 121 and 122 can be switched (the filling degree of the first and second airbags 121 and 122 can be adjusted. If the filling degree of the first capsule 121 is greater than the filling degree of the second capsule 122 in the initial state, gas can be appropriately continued to be injected into the second capsule 122, and the first capsule 121 releases a small amount of gas, so that the filling degree of the first capsule 121 is less than the filling degree of the second capsule 122), so as to reduce the risk of blood circulation being blocked and tissue being damaged due to long-term compression of a certain part of the vaginal inner wall by the airbag.

[0029] A tension ring 13 is provided at the connection between the first bladder body 121 and the second bladder body 122, and the tension ring 13 is made of an elastic material. On the one hand, the airbag part 12 of the balloon structure 1 is in a contracted state when it leaves the factory, which is easy to cause internal adhesion. The tension ring 13 allows the airbag part 12 to maintain an open effect when it leaves the factory, which can reduce the situation where the airbag part 12 cannot expand normally due to internal adhesion; on the other hand, under the action of the tension ring 13, even after the first airbag and the second airbag are expanded, there is still a gap between the two, which can protect the vaginal folds between the first bladder body 121 and the second bladder body 122, and prevent it from being over-clamped by the first bladder body 121 and the second bladder body 122 and causing crushing.

[0030] The support portion 11 is provided with a third catheter 16, one end of which is connected to the first bladder body 121. In laparoscopic hysterectomy, the third catheter 16 of the support portion 11 provides an additional CO2 gas supplement channel. It should be understood that even with the sealing of the airbag structure, tiny gas leaks may still occur at the small incision in the abdomen. After the vaginal vault is incised, CO2 gas is replenished in time through the third catheter 16 to maintain the air pressure in the abdominal cavity and ensure that the patient's abdomen remains in a bulging state. The above operation does not require the injection of CO2 gas through the main channel of the laparoscope, which reduces the pressure on the abdominal incision and its surrounding tissues when replenishing CO2 gas through the main channel, and effectively reduces the risk of tissue damage.

[0031] See also Figure 4 Specifically, according to the above content, this embodiment relates to a uterine lifting forceps 2, which includes a first forceps body 21 and a second forceps body 22 hinged to each other by a rivet 231, and a hysterectomy balloon structure 1 sleeved on the hinged part 23, wherein the first forceps body 21 and the second forceps body 22 both include a forceps arm 221 and a gripping handle 222, the forceps arm 221 of the first forceps body 21 has an arc-shaped head, the forceps arm 221 of the second forceps body 22 has a hook-shaped head, and the forceps arm 221 of the first forceps body 21 is longer than the forceps arm 221 of the second forceps body 22. The first forceps body 21 has an arc-shaped head of the forceps arm 221, which is used to grasp and adjust the position of the cervix of the uterus, and the forceps arm 221 of the second forceps body 22 has a hook-shaped head, which is used to fix and lift the uterus for removal.

[0032] See also Figure 5 - Figure 6The support portion 11 of the balloon structure 1 is provided with a rectangular cross-section mounting channel 112, which is adapted to the outer contour of the cross section at the hinge of the first clamp body 21 and the second clamp body 22, and the length of the rectangular cross section of the mounting channel 112 gradually increases from the middle to the two ends. The mounting channel 112 adopts the above-mentioned design of being narrow in the middle and wide on both sides, and its narrow area is adapted to the hinge part 23 of the uterine lifting forceps 2, and the wide area leaves a margin of movement for the uterine lifting forceps 2 to meet the opening and closing of the first clamp body 21 and the second clamp body 22. Even if the doctor operates the uterine lifting forceps 2 to open and close during surgery, the airbag portion 12 can still maintain good air tightness to prevent abdominal gas leakage.

[0033] The support portion 11 is provided with two sleeves 17 symmetrically at one end close to the first balloon body 121. One end of the two sleeves 17 is connected to the installation channel 112, and the other end is provided with a narrowing ring 171. Both clamp arms 221 are provided with annular positioning grooves 223 adapted to the narrowing ring 171. During the process of installing the balloon structure 1 of the uterine lifting forceps 2, the two clamp arms 221 of the first clamp body 21 and the second clamp body 22 pass through the sleeve 17 and clamp the narrowing ring 171 at the end of the sleeve 17 into the annular positioning groove 223. Under the action of the abdominal cavity air pressure, the narrowing ring 171 is squeezed into the annular positioning groove 223, and the inner side of the installation channel 112 is blocked by the clamp arms 221 and the sleeve 17, so that CO2 gas cannot leak through the hinged part 23 of the uterine lifting forceps 2, and a better sealing effect is achieved without affecting the operation of the uterine lifting forceps 2.

[0034] The inner wall of the installation channel 112 of the balloon structure 1 is symmetrically provided with two U-shaped grooves 113, and two spring pieces 114 are symmetrically provided in the U-shaped grooves 113. The two U-shaped grooves 113 are snap-fitted with two guide posts 232 symmetrically provided on both sides of the hinged part 23 of the uterine lifting forceps 2, and the spring pieces 114 squeeze and fix the guide posts 232. When the balloon structure 1 is installed, the U-shaped grooves 113 and the spring pieces 114 form a mechanical locking mechanism, which locks the guide posts 232 and ensures the fixation of the balloon structure 1 on the uterine lifting forceps 2. This prevents the balloon structure 1 from falling off due to the need to adjust the depth of the uterine lifting forceps 2 when the doctor is operating the uterine lifting forceps 2.

[0035] The tube sleeve 17 is made of a flexible material, and the junction of the two tube sleeves 17 is sealed and detached from the support part 11. When the balloon structure 1 is inflated and fixed in the vagina, the doctor still needs to operate the uterine lifting forceps 2 to move or swing. At this time, the tube sleeve 17 is made of a flexible material and can be elastically stretched. Because the junction of the two tube sleeves 17 is sealed and detached from the support part 11, when the position of the balloon structure 1 is fixed, the tube sleeve 17 can independently follow the position change of the hinge part 23 of the uterine lifting forceps 2 and expand and contract, ensuring the doctor's operating space for the uterine lifting forceps 2.

[0036] The first clamp body 21 and the second clamp body 22 are made of corrosion-resistant materials. In this embodiment, the first clamp body 21 and the second clamp body 22 are both made of titanium alloy or medical stainless steel alloy. Selecting appropriate corrosion-resistant materials can improve the compatibility of the instrument with human tissue and reduce the risk of postoperative complications.

[0037] Specifically, the method of using the uterine lifting forceps 2 of this embodiment is as follows:

[0038] (1) Preparation: The doctor should first prepare the necessary instruments, including uterine forceps, syringes and their tubing sets, disinfectants, gloves, etc. Ensure that all instruments are properly disinfected and cleaned.

[0039] (2) Preoperative evaluation: The physician should carefully evaluate the patient's condition and medical history and determine the appropriate circumstances for the use of a uterine manipulator. 2 This may require a detailed obstetric examination and other relevant examinations.

[0040] (3) Anesthesia: As needed, the doctor may give the patient local anesthesia or general anesthesia to provide a comfortable and painless surgical environment.

[0041] (4) Inserting the balloon structure 1: The doctor should wear gloves and hold the uterine forceps 2 in his hand, insert the balloon structure 1 into the uterine forceps 2, so that the balloon structure 1 is fixed to the hinge part 23 of the uterine forceps 2, and the catheter of the balloon structure 1 is connected to the syringe.

[0042] (5) Inflation and sealing: The doctor inserts the head of the second clamp body 22 of the uterine lifting forceps 2 into the cervical opening, and clamps the cervix with the clamp arm 221 of the first clamp body 21 of the uterine lifting forceps 2, pushes the syringe piston to expand the balloon structure 1 to seal the vagina, and if necessary, replenishes CO2 gas through the third catheter 16.

[0043] (6) Lifting the cervix: The doctor gently lifts the cervix with appropriate techniques and strength to keep it stable. This helps provide a better view and operating space.

[0044] (7) Surgical operation: Hysterectomy is performed with the cervix lifted. The doctor should choose the appropriate operation method and instruments according to the specific situation and surgical needs.

[0045] (8) Completion of the operation: After the operation, the doctor extracts gas by pulling the syringe piston to shrink the balloon structure 1, and then carefully removes the uterine forceps 2 from the cervix, making sure that no instruments or other objects are left behind, and removes the balloon structure 1 from the uterine forceps 2.
