Description

Technical Field

[0001] The invention belongs to the technical field of life science and veterinary medicine, and in particular relates to a small animal single-hole multi-channel endoscope system. Background Art

[0002] Since the laparoscopic technology was applied to surgical operations in the 1980s, endoscopic technology has been increasingly widely used in human surgery, and has further developed into various variants with different functions, such as 3D laparoscopes, 4K laparoscopes, fluorescent laparoscopes, and robot-assisted laparoscopes, which have shined in different fields such as abdominal surgery, thoracic surgery, urology, and gynecology, and have achieved minimally invasive and refined human surgery. In recent years, with the advancement of materials and surgical techniques, single-port laparoscopes with less trauma have gained more favor due to their characteristics of small scars (skin incisions of about 1-3 cm), and have gradually replaced traditional laparoscopes in the surgical treatment of some diseases in gynecology, thoracic surgery, and general surgery.

[0003] Currently, there are many brands and specifications of single-port laparoscopic puncture devices, but their general structures are similar. They are mainly composed of a ring and a multi-channel platform. The ring is divided into an inner ring and an outer ring, which are connected by a rubber sleeve. When used, the flexible inner ring is inserted into the abdominal cavity through an incision, and then the hard outer ring is turned down to the skin surface to form a through channel and clamp the skin tightly. Then the multi-channel platform and the outer ring are clamped and connected, which limits the size of the ring to about 3-5cm, and it is difficult to further reduce it, so it cannot be used in similar surgical operations on small animals.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figure 1-Figure 2 As shown, this embodiment provides a small animal single-port multi-channel endoscope system, including a channel body, the channel body including a base 1 adapted to the abdominal cavity, the base 1 is detachably connected to a connecting seat, the connecting seat is located on the outside of the abdominal cavity, and the side of the connecting seat away from the base 1 is respectively connected to an air supply mechanism, an operating mechanism and an observation mechanism, the operating mechanism includes an operating head 2 that passes through the connecting seat and the base 1 in sequence and extends into the abdominal cavity, and the observation mechanism includes an observation head 3 that passes through the connecting seat and the base 1 in sequence and extends into the abdominal cavity.

[0020] The present invention is mainly used in small animal life science research, disease diagnosis and treatment. The air supply mechanism, operating mechanism and observation mechanism are respectively connected through a connecting seat, thereby realizing relatively complex abdominal exploration and operation through a single tiny incision, which greatly reduces surgical trauma compared to conventional open operation.

[0021] Due to its tiny size, this system can be used for direct exploration of abdominal lesions in small animals such as mice. In the field of life science research, it solves the problem that abdominal lesions in model animals are difficult to directly explore through minimally invasive means. It can also relatively easily perform operations such as lesion sampling and drug injection under direct vision, expanding the establishment and evaluation methods of mouse abdominal lesion-related models.

[0022] At the same time, the system can also be used for the diagnosis and treatment of intra-abdominal diseases in small animals. In the field of pet medicine, it can be used for the exploration, diagnosis and treatment of intra-abdominal diseases in small exotic pets and common pets such as cats and dogs.

[0023] A further optimized solution is that the connecting seat includes a connecting head 4, a connecting block 5 and a connecting platform 6 which are connected and communicated in sequence. The connecting head 4 is detachably connected to the base 1. The side of the connecting head 4 away from the base 1 is fixedly connected to the connecting block 5. The side of the connecting block 5 away from the connecting head 4 is provided with a first groove 7, and the connecting platform 6 is fixedly connected in the first groove 7.

[0024] According to a further optimized solution, the connecting platform 6 is connected to the operating head 2, the observation head 3 and the air supply mechanism through the sealing seat 8 respectively.

[0025] The connecting platform 6 is a hemispherical rubber sleeve with a certain degree of ductility. The bottom surface of the hemispherical rubber sleeve is closed inward and connected to the first groove 7 of the connecting block 5 through a ring. Several protrusions are extended on the connecting platform 6 as the lens 10, the operating head 2 and the air supply channel. A rubber sealing seat 8 is installed on each protrusion to prevent air leakage.

[0026] To further optimize the solution, traction ropes 9 are fixedly connected to both ends of the base 1.

[0027] The base 1 is a flexible annular structure that can be radially compressed to facilitate entry into the abdominal cavity through a small incision. A traction rope 9 is installed on both sides of the outside of the base 1, which is radially symmetrical and is used to play a traction role when connected to the connecting seat to prevent the base 1 from twisting and shifting in the abdominal cavity. At the same time, it can pull the abdominal muscles and skin apart, and prevent the intestines and other abdominal organs from sliding into the gap between the base 1 and the connecting seat when they are combined and squeezed. The inner surface of the base 1 is truncated inward to push away the organs below after the channel enters the abdominal cavity, create operating space and provide directionality, and at the same time be used for the connecting seat and the base 1 to be clamped and connected.

[0028] In a further optimized solution, the observation head 3 is a cold light source extending into the abdominal cavity, and the end of the observation head 3 away from the abdominal cavity is electrically connected to a lens 10, the lens 10 is located outside the abdominal cavity, and the end of the lens 10 away from the observation head 3 is electrically connected to a display 11. It can provide intra-abdominal illumination and image acquisition and display.

[0029] In a further optimized solution, the gas supply mechanism includes a first connecting pipe 13 connected to the connecting platform 6, one end of the first connecting pipe 13 away from the connecting platform 6 is connected to a gas source, and a gas valve 14 and a filter 15 are respectively provided on the first connecting pipe 13, and the gas valve 14 and the filter 15 are respectively located on the outside of the connecting platform 6. Low-pressure CO2 gas can be continuously provided to establish pneumoperitoneum.

[0030] According to a further optimized solution, the base 1 is a flexible ring-shaped structure, and the connector 4 is a flexible tower-shaped structure.

[0031] The connector 4 is a flexible tower-shaped structure, which can pass through the inner ring of the base 1 and be clamped therewith by external force to form a closed structure.

[0032] When the channel is used, the base 1 is radially compressed and placed in the abdominal cavity, and then the position is fixed by pulling the traction rope 9 and the connection seat is connected to it. The connection seat is placed outside the abdominal cavity, and is connected and clamped with the base 1 through the connector 4, so that the operation head 2 can be provided in the abdominal cavity. The channel is sealed to prevent air leakage.
