Description

Technical Field

[0001] The utility model relates to the technical field of surgical tools, and more specifically, to a spatula forceps. Background Art

[0002] The spatula forceps, also called the tubular forceps, are commonly used for clamping excised masses in laparoscopic surgery. At present, the spatula forceps do not have the functions of electrosection and electrocoagulation. During the process of excising a mass in laparoscopic surgery, steps such as separating tissues, cutting, and taking specimens are required. During this period, due to repeated bleeding of the tissues, an electrocoagulation device needs to be used to stop bleeding at the bleeding points. The spatula forceps and the electrocoagulation device are replaced frequently. The time difference generated during the replacement process will cause rebleeding, which will further lead to the inability to accurately judge the bleeding point, increasing the surgical difficulty and operation time, and also increasing the surgical risk. Therefore, it is urgent to improve this situation. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1 to 3 shown, a spoon-shaped clamp includes a working section 1, a connecting pipe 2, a driving section 3, and an electrocoagulator 8. The working section 1 and the driving section 3 are connected by the connecting pipe 2. The working section 1 includes a fixed sleeve 6 and a movable clamp 7. The fixed sleeve 6 and the movable clamp 7 are hinged. A fixed clamp 61 is provided on the side of the fixed sleeve 6. The movable clamp 7 can abut against or move away from the fixed clamp 61. The driving section 3 includes a fixed arm 4 and a movable arm 5. The fixed arm 4 and the movable arm 5 are hinged by a first hinge portion 31. The movable arm 5 is connected to the movable clamp 7 by a connecting rod 9. The movable arm 5 can pull the connecting rod 9 to move, so that the movable clamp 7 abuts against the fixed clamp 61. A second through hole 62 is provided inside the fixed sleeve 6. A pin shaft 63 and a third hinge portion 64 are provided inside the second through hole 62. A connecting piece 71 is provided at the tail end of the movable clamp 7. The connecting piece 71 is hinged to the fixed sleeve 6 by the pin shaft 63. The connecting piece 71 is hinged to the connecting rod 9 by the third hinge portion 64. The third hinge portion 64 is located on the side of the pin shaft 63 away from the head end of the movable clamp 7. The movable arm 5 includes an avoidance groove 51. A second hinge portion 52 is provided inside the avoidance groove 51. The connecting rod 9 sequentially passes through the second through hole 62, the connecting pipe 2, the fixed arm 4, and is inserted into the avoidance groove 51 and hinged to the avoidance groove 51 by the second hinge portion 52.

[0021] During use, when the movable arm 5 moves along the first hinge portion 31 and the holding portion of the movable arm 5 approaches the fixed arm 4, the movable arm 5 can pull the connecting rod 9 to move toward the side away from the working section 1. At this time, the connecting rod 9 can pull the connecting piece 71 to move, so that the movable clamp 7 rotates along the pin shaft 63, so that the movable clamp 7 abuts against the fixed clamp 61 to achieve the clamping operation.

[0022] The electrocoagulator 8 includes an electrode head 81 which is located inside the movable clamp 7. Specifically, a second installation groove 72 is provided inside the movable clamp 7, and the electrode head 81 is inserted into the second installation groove 72. The electrode head 81 can be separated from the second installation groove 72. The electrocoagulator 8 includes a wire harness 82. One end of the wire harness 82 is connected to the electrode head 81 and the other end passes through the second through hole 62, the connecting pipe 2, and the fixed arm 4 respectively. The movable arm 5 includes a first through hole 53 and a first installation groove 54. A connecting head 83 is installed in the first installation groove 54. The wire harness 82 passes through the first through hole 53 and is connected to the connecting head 83. The movable clamp 7 is made of a metal part and can conduct electricity. The outside of the connecting head 83 is connected to a device for controlling electrocoagulation and electrosection (not shown in the figure). By installing the electrode head 81 in the second installation groove 72, the electrocoagulation and electrosection functions of the movable clamp 7 can be realized. During laparoscopic surgery, while clamping a tumor, monopolar electrosection and electrocoagulation can be performed, thereby reducing bleeding during tissue cutting during the operation, and the steps of electrosection, electrocoagulation, and removing the tumor tissue can be completed at one time, greatly reducing the operation time. It is applicable to the resection operation of tumors under laparoscopy. Among them, the device for controlling electrocoagulation and electrosection is prior art, and its specific structure will not be elaborated in this specification.

[0023] Both the working section 1 and the driving section 3 are made of metal materials, and the connecting pipe 2 and the connecting rod 9 are made of plastic materials. Through the above design, while ensuring the structural strength, electrical conduction is prevented.

[0024] The fixed arm 4 includes an annular sleeve 41. One end of the connecting pipe 2 is inserted into the fixed sleeve 6 and the other end is inserted into the annular sleeve 41. Specifically, annular platforms 21 are provided at both ends of the connecting pipe 2. One annular platform 21 is inserted into the fixed sleeve 6 and the other annular platform 21 is inserted into the annular sleeve 41. The outer contours of the connecting pipe 2, the fixed arm 4, and the annular sleeve 41 are flush. The connecting pipe 2 is formed by injection molding and combined with the working section 1 and the driving section 3. Through the above design, the connection strength between the connecting pipe 2 and the working section 1 and the driving section 3 is greatly improved.
