Description

Technical Field

[0001] The present invention relates to the field of an endoscope top component for emergency treatment of gastric fundus fold failure, and in particular to an endoscope top component for emergency treatment of gastric fundus fold failure. Background Art

[0002] The gastric fundus folding endoscope is a medical device used to treat gastroesophageal reflux disease. The anvil is connected to the top. The existing connection process between the anvil and the top is to use screws to position and fix the two.

[0003] The existing connection process between the anvil and the top end will cause two problems if used for endoscopes to treat gastroesophageal reflux disease: first, the screws are higher than the surface of the anvil, which increases the chance of harming the human body when the instrument is inserted into the human body; second, if the anvil screws cannot be retracted during the operation, the anvil and the top end cannot be quickly separated to withdraw the instrument from the human body, causing greater damage to the human body.

[0004] For medical devices, the protection of the human body and the minimization of damage caused by possible device failure are the top priorities, and the previous connection structure between the cutting board and the top has obvious defects in these aspects. Summary of the invention

[0005] The present invention provides an endoscope top assembly for emergency treatment when gastric fundus folding fails, which will solve the technical problem in the prior art that the chopping board and the top cannot be quickly separated when the chopping board and the top cannot be retracted.

[0006] The technical solution provided by the present invention is as follows:

[0007] An endoscope top assembly for emergency treatment of gastric fundus fold failure, comprising:

[0008] A connecting piece, wherein one end of the connecting piece is provided with a mounting groove, and a side wall of one end of the connecting piece close to the mounting groove is provided with at least two mounting holes penetrating the connecting piece, and the mounting holes are in communication with the mounting groove;

[0009] An anvil is placed in the mounting groove, and the anvil is provided with a mounting position matching the mounting hole;

[0010] A pin passes through the installation hole and engages with the installation position to fix the cutting board and the connecting piece.

[0011] In this technical solution, by opening a mounting groove on the connector and a mounting hole communicating with the mounting groove, a mounting position matching the mounting hole is set on the anvil, and the anvil is placed in the mounting groove and fixed by a pin. When disassembling the anvil and the connector, it is only necessary to push the pin out of the mounting hole to separate the pin from the mounting position. The operation is convenient and quick, so that during the operation, when the anvil is engaged with other parts of the external instrument, the anvil can be quickly separated from the connector by pushing out the pin. The error correction time after the instrument is engaged is greatly reduced, thereby reducing secondary damage to the patient, reducing the risk of surgery, and increasing the success rate of surgery.

[0012] Preferably, the mounting hole is divided into a first section and a second section, and the first section and the second section are located on both sides of the mounting groove.

[0013] In the present technical solution, the mounting hole is divided into two sections, namely the first section and the second section, and the first section and the second section are respectively located on both sides of the mounting hole, so that during installation, the mounting position can be better located in the same straight line with the mounting hole, ensuring that the pin, the mounting hole and the mounting position can be well connected together, thereby achieving a good fixing effect.

[0014] Preferably, a fixing hole forming the mounting position is opened on the side wall of the anvil, and the fixing hole is connected to the first section and the second section of the mounting hole, so that the pin passes through the first section, the fixing hole and the second section in sequence to fix the anvil and the connecting member.

[0015] In the present technical solution, a fixing hole is opened on the side wall of the chopping board. When the chopping board is placed in the mounting groove, the mounting hole and the fixing hole are located on a first straight line. When in use, the pin passes through the first section, the fixing hole and the second section of the mounting hole in sequence, thereby fixing the chopping board and the connecting piece. Disassembly is also very convenient and quick.

[0016] Preferably, a section of the mounting hole located in the mounting groove is an arc-shaped structure.

[0017] Preferably, a protrusion extends outward from the side wall of the anvil corresponding to the position of the mounting hole, and the pin is a tubular structure with a notch axially opened along the side wall of the pin, so that when the pin is inserted along the mounting hole, the mounting hole is located inside the pin.

[0018] In the present technical solution, a protrusion is extended from the side wall of the anvil corresponding to the position of the mounting hole, and the pin is a tubular structure with a notch axially opened along the side wall of the pin. When the pin is inserted into the socket, the protrusion enters the interior of the pin along the mounting position to fix the anvil on the connecting piece, which can achieve a good fixing effect.

[0019] Preferably, an arcuate groove forming a mounting position is provided on the anvil board corresponding to the mounting hole, so that when the anvil board is placed in the mounting groove, a section of the pin located in the mounting groove is partially located in the arcuate groove and partially located in the mounting hole.

[0020] In this technical solution, after placing the cutting board on the mounting groove and inserting the pin, the pin is located in a section of the mounting groove, part of which is located in the mounting hole and part of which is located in the arc groove, so as to realize the locking and limiting of the cutting board, thereby fixing the cutting board.

[0021] Preferably, the mounting groove is an arc-shaped structure, and the fitting surface between the anvil board and the mounting groove is an arc-shaped structure.

[0022] Preferably, the mounting positions are arranged close to both ends of the arc of the anvil board.

[0023] In this technical solution, by setting installation positions at both ends of the arc of the chopping board, interference with other connecting structures is avoided, and the position of the connecting piece is utilized to the maximum extent, so that the connecting piece can be well connected to the chopping board without affecting the use of the chopping board and other structures.

[0024] Preferably, the cutting board comprises:

[0025] A connecting portion, the connecting portion is an arc-shaped structure, and the connecting portion matches the notch of the mounting slot;

[0026] A fixing portion, wherein the fixing portion is located in the mounting groove, and the mounting position is arranged on the fixing portion.

[0027] Preferably, the length of the pin is slightly smaller than the length of the mounting hole.

[0028] In the present technical solution, the pin is set to be smaller than the length of the mounting hole so that the top assembly of the endoscope for fundus folding does not increase the axial dimensions of the endoscope and the outer dimensions of the part inserted into the human body during use, thereby greatly reducing the damage to the human body caused by the endoscope after entering the human body.

[0029] Compared with the prior art, the embodiment of the endoscope top assembly for emergency treatment of gastric fundus fold failure provided by the present invention has the following beneficial effects:

[0030] 1. In the present invention, if the situation that the screw of the anvil cannot be withdrawn during the operation is encountered, the pin can be pushed out of the mounting hole to achieve rapid separation of the anvil and the connecting piece, so that the instrument can be withdrawn from the human body, thereby shortening the operation time for the engagement of the instrument and reducing damage to the patient. On the other hand, the use of a pin to connect the anvil and the top is also very quick and convenient during assembly.

[0031] 2. The length of the pin used in the present invention is smaller than the length of the mounting hole, and all other components are inside the endoscope for fundus folding, without increasing the axial length of the endoscope and the outer dimensions of the part inserted into the human body, which greatly reduces the damage to the human body caused by the endoscope after entering the human body.

[0032] 3. In the present invention, the anvil board is limited by providing an installation groove to prevent the anvil board from shaking on the connection, and a pin is used to fix the anvil board to prevent the anvil board from shaking along the axial direction of the connecting piece. The dual limitation of the installation groove and the pin makes the connection between the anvil board and the connecting piece tighter, avoiding the loosening of the anvil board and the connecting piece during use, which may affect the operation.

[0049] According to an embodiment provided by the present invention, Figure 1 As shown, an endoscope top assembly for emergency treatment when fundus folding fails, includes: a connector 200, an anvil 100 and a pin, one end of the connector 200 is provided with a mounting groove 210, and the side wall of the connector 200 at one end close to the mounting groove 210 is provided with at least two mounting holes 240 penetrating the connector 200, and the mounting holes 240 are communicated with the mounting groove 210; the anvil 100 is placed in the mounting groove 210, and the anvil 100 is provided with a mounting position matching the mounting hole 240; the pin passes through the mounting hole and engages with the mounting position to fix the anvil 100 and the connector 200. In this embodiment, the connection between the pin and the mounting hole 240 is an interference fit, so that the pin will not fall off during the operation, thereby avoiding surgical risks caused by the pin falling off during the operation.

[0050] Specifically, the mounting groove 210 is an arc-shaped structure, and the mating surface between the anvil 100 and the mounting groove 210 is an arc-shaped structure. In implementation, one end of the connector 200 where the mounting groove 210 is provided is also an arc-shaped structure, and an arc-shaped groove is provided thereon, and the mounting position is arranged near both ends of the arc of the anvil 100, and the length of the pin is slightly smaller than the length of the mounting hole 240;

[0051] In actual implementation, a positioning hole 220 is opened on the connecting piece 200 next to the mounting groove 210, and a positioning pin is arranged in the positioning hole 220. By setting the positioning hole 220 and the positioning pin in the positioning hole 220, the top end assembly of the endoscope for fundus folding can quickly play a role in aligning with the matching instrument during use, so that the gastroesophageal reflux surgery can be performed faster, shortening the operation time, and thus achieving better surgical results. A first fixing hole 230 is provided on the connecting member 200 beside the mounting groove 210 for installing an ultrasonic instrument to assist surgery and increase the success rate of the surgery. Similarly, an air flow hole 260 and a liquid output hole are provided on the connecting member 200 beside the mounting groove 210, as well as a second fixing hole 280 for installing an LED lamp and a third fixing hole 290 for installing a micro camera. During actual installation, the positioning hole 220 and the first fixing hole 230 for installing the ultrasonic instrument are located on one side of the mounting groove 210, and the air flow hole 260, the delivery hole 270, the second fixing hole 280, and the third fixing hole 290 are located on the other side of the mounting groove 210.

[0052] In a specific implementation, the chopping board 100 includes: a connecting portion 110 and a fixing portion 120, the connecting portion 110 is an arc-shaped structure, and the connecting portion 110 matches the notch of the mounting groove 210; the fixing portion 120 is located in the mounting groove 210, and the mounting position is set on the fixing portion 120. In implementation, the mounting position can be set at both ends of the arc of the fixing portion 120 close to the connecting portion 110, or can be set along the arc groove 160. At the same time, two shielding portions are also provided on the side wall of the fixing portion 120, namely, a first shielding portion 140 and a second shielding portion 150. The first shielding portion 140 corresponds to the airflow hole 260, and the second shielding portion 150 corresponds to the delivery hole 270. The first shielding portion 140 blocks the airflow hole 260, and the second shielding portion 150 blocks the delivery hole 270, so as to change the flow direction of the airflow and the liquid;

[0053] At the same time, two screw holes 130 are provided on the anvil board 100 for installing screws. When in use, the two screws are positioned relative to the matching instruments to perform gastroesophageal reflux surgery. The connector 200 is provided with placement holes 250 corresponding to the two screw holes 130, so that the screws can be better set on the anvil board 100. In the present embodiment, the specific opening method of the mounting holes 240 is not limited. It is only required that the mounting holes 240 after opening can allow the pins to be inserted to connect the connector 200 and the anvil board 100. Similarly, the present embodiment does not limit the specific setting method of the mounting position and the specific setting method of the pin. In the present embodiment, it is only required that the pins set can connect the anvil board 100 and the connector 200.

[0056] In another embodiment of the present invention, a section of mounting hole 240 located in mounting groove 210 is an arc-shaped structure, and an arc-shaped groove 160 forming a mounting position is opened on the anvil 100 corresponding to mounting hole 240, so that when the anvil 100 is placed in mounting groove 210, a section of the pin located in mounting groove 210 is partially located in arc-shaped groove 160 and partially located in mounting hole 240. In specific implementation, mounting hole 240 of the arc-shaped structure is adapted to arc-shaped groove 160. During the specific installation process, the pin is inserted into mounting hole 240 and the pin is located in the mounting hole 240. A section within groove 210 is partially located within mounting hole 240 and partially located within arc groove 160. In the present embodiment, arc groove 160 is of a semicircular structure, which coincides with the portion cut off from mounting hole 240. When anvil 100 is placed within mounting groove 210, the arc groove of the semicircular structure is sealed on the opening of mounting hole 240, so that the connected anvil 100 and connector 200 will not shake, and the connection is very tight, thus avoiding looseness between anvil 100 and connector 200 during surgery and causing medical accidents.

[0057] It should be noted that, in the specific implementation, it is not limited to the opening method of the mounting hole 240, the design method of the mounting position, and the design method of the pin in the present application document. As long as the mounting position and the mounting hole 240 are connected by a pin to achieve the connection between the anvil 100 and the connecting member 200, they are all protected objects in the present application document. In implementation, the mounting hole 240 can be opened along the arc direction of the mounting groove 210, and the mounting position is set close to the two side edges of the mounting groove 210. This application document will not go into too much detail on this.

[0058] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
