Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tip cap used in endoscopic surgery of the digestive system. Background Art

[0002] With the continuous advancement of medical technology, endoscopic technology has become an important means of diagnosis and treatment of digestive system diseases. Compared with traditional open surgery, minimally invasive surgery has the advantages of less trauma, faster recovery, and fewer complications, so it has been widely used. However, in actual operation, endoscopic surgery also faces some challenges. For example, when removing tumors in the digestive system, due to the limitations of the endoscopic field of view, the edge of the tumor may be difficult to be accurately identified, resulting in the collapse or movement of the tumor edge during the operation. This not only increases the difficulty of the operation, but may also affect the results of the operation and even increase the risk to the patient.

[0003] At present, most endoscopic-assisted tools cannot effectively maintain the stability of the tumor during surgery. On the one hand, the edge of the tumor collapses or moves when the tumor is removed, which makes the surgical operation complicated and increases the risk of surgical failure. On the other hand, in order to maintain a clear field of vision, the position of the endoscope may need to be constantly adjusted during the operation, which not only prolongs the operation time but also increases the difficulty of the doctor's operation. Therefore, it is necessary to develop a new endoscopic-assisted tool that can stabilize the edge of the tumor during surgery and reduce the frequency of endoscope adjustment. This is of great significance to improving the safety and efficiency of endoscopic surgery. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 , the utility model provides a technical solution: a tip cap used in digestive system endoscopic surgery, comprising an endoscope body 1, on which an auxiliary mechanism 200 for stretching the mucosa and expanding the field of vision is installed;

[0024] Through the mutual cooperation of the auxiliary mechanisms 200 on the endoscope body 1, a design of an openable and closable transparent cap is provided. This design allows the doctor to stabilize and expose the tumor by controlling the opening and closing of the cap when removing the tumor, which can ensure that the tumor always remains in a relatively stable and easy-to-operate position during the operation, thereby reducing the difficulty of the operation and reducing the risk of the operation. At the same time, it can ensure that the doctor's line of sight during the operation is not obstructed, improve the safety of the operation, and quickly adapt to different surgical environments and surgical needs, thereby improving the efficiency and success rate of the operation.

[0025] In this embodiment, the auxiliary mechanism 200 is a structure used to ensure that the tumor is always kept in a relatively stable and easy-to-operate position during the operation.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the auxiliary mechanism 200 includes two groups of traction components and a first connecting and pulling component and a second connecting and pulling component respectively connected to the two groups of traction components, and one end of the first connecting and pulling component and the second connecting and pulling component are both connected to the opening and closing component;

[0027] The traction assembly is connected to the opening and closing assembly through the No. 1 connecting and pulling assembly and the No. 2 connecting and pulling assembly. The traction assembly pulls the No. 1 connecting and pulling assembly and the No. 2 connecting and pulling assembly to move, and drives the opening and closing assembly to open and close under the traction action.

[0028] The auxiliary mechanism 200 is designed to effectively expand the surgical field of view by stretching the digestive tract mucosa. It can automatically stretch the mucosa when performing tissue resection in the submucosal layer. This function not only provides a larger surgical field of view, but also can effectively pull the mucosa physically to facilitate the precise execution of surgical operations.

[0029] It should be noted that the traction assembly includes a tube 2011, an auxiliary buckle 2012, a guide tube 2013 and a pull ring 2014; one end of the tube 2011 is fixedly connected to one end of the auxiliary buckle 2012, and the other end is fitted with one side of the pull ring 2014; the side of the auxiliary buckle 2012 away from the tube 2011 is fixedly connected to one side of the guide tube 2013, and one side of the No. 1 connecting and pulling assembly passes through the guide tube 2013, the auxiliary buckle 2012 and the tube 2011 in sequence and extends to one side of the pull ring 2014 and is connected to the pull ring 2014. This is for the endoscope operator to manually pull the pull ring 2014 to drive the No. 1 connecting and pulling assembly to move, so that the operator can accurately control the opening and closing degree of the opening and closing assembly according to the surgical needs, and realize precise control of traction and field of view expansion. This manual control method provides great flexibility and accuracy for the surgical operator, ensuring the smooth progress of the surgical process.

[0030] It can be understood that the No. 1 connecting pulling assembly includes a No. 1 main traction rope 2021, a No. 1 slave traction rope 2022 and a No. 2 slave traction rope 2023; one end of the No. 1 main traction rope 2021 is fixedly connected to one side of one of the pull rings 2014, and the other end is fixedly connected to one end of the No. 1 slave traction rope 2022 and the No. 2 slave traction rope 2023 respectively. The other ends of the No. 1 slave traction rope 2022 and the No. 2 slave traction rope 2023 are both connected to the opening and closing assembly in order to play a traction role on the opening and closing assembly, and the opening and closing of the opening and closing assembly is realized through its opening and closing action. This opening and closing action can be precisely controlled to achieve appropriate stretching of the mucosa of the surgical area, thereby optimizing the surgical operating environment. This design not only improves the accuracy of the operation, but also ensures the clarity of the surgical field of view, and provides a good operating platform for the surgical operator.

[0031] In addition, the No. 2 connecting pulling assembly includes a No. 2 main traction rope 2031, a No. 3 slave traction rope 2032 and a No. 4 slave traction rope 2033; one end of the No. 2 main traction rope 2031 is fixedly connected to one side of another pull ring 2014, and the other end is fixedly connected to one end of the No. 3 slave traction rope 2032 and the No. 4 slave traction rope 2033 respectively, and the other ends of the No. 3 slave traction rope 2032 and the No. 4 slave traction rope 2033 are both connected to the opening and closing assembly, in order to meet the different traction requirements of the mucosa in endoscopic surgery of the digestive system. This design takes into account the operating comfort during the operation, ensuring that the contact between the opening and closing assembly and the digestive tract mucosa is both effective and will not cause discomfort to the operator. Through this design, the opening and closing assembly can provide the operator with a stable and comfortable operating experience throughout the operation.

[0032] In this embodiment, the opening and closing assembly includes a mounting fixing ring 2041, a transparent opening and closing cap body 2042 and an elastic plate 2043; the inner side of the mounting fixing ring 2041 is fixedly mounted at the outer port of the endoscope body 1, one side of the transparent opening and closing cap body 2042 is fixedly connected to one side of the mounting fixing ring 2041, and the number of transparent opening and closing cap bodies 2042 is four and is evenly distributed in a circle with the axis of the mounting fixing ring 2041 as the axis center, one side of the elastic plate 2043 is fixedly connected to one side of the mounting fixing ring 2041, and There are multiple elastic plates 2043 and they are evenly distributed in a circle with the axis of the mounting fixing ring 2041 as the center. The transparent opening and closing cap body 2042 is made of highly transparent material to ensure that the surgical field of view is clearly visible. The transparent opening and closing cap body has a certain rigidity to maintain its shape stability. At the same time, the traction effect is achieved through the elastic properties of the material. The selection and design of this material ensure that the tip cap will not interfere with the field of view of the endoscope while providing effective traction, and can maintain a stable shape during the operation.

[0033] It should also be noted that one side of the elastic plate 2043 is attached to one side of the transparent opening and closing cap body 2042 so that the transparent opening and closing cap body 2042 has an elastic recovery mechanism during the traction operation. This mechanism ensures that after the operation is completed, the transparent opening and closing cap body 2042 can be restored to its original state, thereby maintaining the stability of the surgical field of view and the continuity of the traction force. This design not only improves the durability of the transparent opening and closing cap body 2042, but also ensures the stability of the surgical field of view, providing a continuous and stable operating environment for the surgical operator.

[0034] The working principle of the above embodiment is:

[0035] 1. Preparation stage: Before the operation begins, make sure that all equipment is ready. First, fix the transparent opening and closing cap 2042 in a closed state to the tip of the endoscope body 1 used for the operation. This step is very critical because the degree of fixation of the transparent opening and closing cap 2042 will directly affect the clarity of the surgical field and the accuracy of the operation. Make sure that the transparent opening and closing cap 2042 is firmly connected to the endoscope body 1 without shaking to ensure stability during the operation;

[0036] 2. Entering the body: The operator slowly and steadily inserts the endoscope body 1 into the patient's body until it reaches the predetermined surgical position. During this process, the operator needs to closely monitor the images transmitted back by the endoscope body 1 to ensure that the path of the endoscope body 1 is correct. After reaching the target position, the operator will pause the advancement of the endoscope body 1 and prepare for the next operation;

[0037] 3. Tumor removal: After confirming that the endoscope body 1 has been stably located at the target position, the operator begins to adjust the opening and closing state of the transparent opening and closing cap 2042 according to the specific situation of the tumor. At this time, the two pull rings 2014 are pulled at the same time to respectively drive the No. 1 main traction rope 2021 and the No. 1 slave traction rope 2022 to move, so that the transparent opening and closing cap 2042 is driven to open and close under the traction of the No. 1 slave traction rope 2022, the No. 2 slave traction rope 2023, the No. 3 slave traction rope 2032 and the No. 4 slave traction rope 2033. The adjustment of the opening and closing degree is to ensure the clarity of the surgical field of view, and at the same time enable the operator to stably control the transparent opening and closing cap 2042, thereby better removing the tumor. The opening and closing state of the transparent opening and closing cap 2042 can be finely adjusted according to the needs of the operation to adapt to different surgical environments and characteristics of the tumor;

[0038] 4. Completion of resection: With the complete resection of the tumor, the operator needs to loosen the pull ring 2014. Under the elastic potential energy rebound force of the elastic plate 2043, the transparent opening and closing cap 2042 can be adjusted to return to the closed state to ensure that the endoscope body 1 can be safely withdrawn from the body. This step also requires precise control to avoid residual tumor fragments or surgical instruments from damaging surrounding healthy tissues. After completing the adjustment, the operator can start the withdrawal procedure of the endoscope body 1 to ensure a safe and smooth operation.

[0039] Compared with the prior art: the tip cap used in digestive system endoscopic surgery provides a design of an openable and closable transparent cap through the mutual cooperation of the auxiliary mechanism 200 on the endoscope body 1. This design allows the doctor to stabilize and expose the tumor by controlling the opening and closing of the cap body when removing the tumor, which can ensure that the tumor is always kept in a relatively stable and easy-to-operate position during the operation, thereby reducing the difficulty of the operation and reducing the risk of the operation. At the same time, it can ensure that the doctor's line of sight during the operation is not obstructed, improve the safety of the operation, and quickly adapt to different surgical environments and surgical needs, thereby improving the efficiency and success rate of the operation, and solving the problems of existing endoscopic auxiliary tools when removing tumors, such as the collapse of the tumor edge or the movement of the position, and the need to constantly adjust the position of the endoscope.
