AI Technical Summary
Thoracoscopic surgery requires prolonged holding in the air during use, causing arm soreness and swelling for medical staff, and existing fixation devices may cause pressure injury to patients.
An auxiliary fixation device comprising an embedded part, a positioning part, and a restraint part was designed. The embedded part is made of a soft silicone tube. The positioning part is fixed to the patient's body surface through a base and a through groove. The restraint part ensures stability, distributes gripping force, and is reusable through an adhesive surface and a flat edge.
It effectively distributes gripping force, reduces fatigue of medical staff, minimizes harm to patients, increases ease of operation, and reduces usage costs.

Abstract
Claims
1. A surgical thoracoscopic assisted fixation device, characterized by: The device includes an embedded part (1), a positioning part (2), and a restraining part (3). The positioning part (2) includes a base (201) with an insertion hole (208) in the center. The embedded part (1) includes a flexible tube (101) fixedly connected to the bottom surface of the base (201). The inner wall of the flexible tube (101) is aligned with the inner wall of the insertion hole (208). The base (201) has a through groove (202) that passes through the upper and lower surfaces. The restraining part (3) is adapted to fix the positioning part (2) to the surface of the surgical object. The restraining part (3) includes a connecting cover (301) located on the upper surface of the base (201). The connecting cover (301) has an insertion port (302) that runs through the upper and lower surfaces in the center. The side of the connecting cover (301) is connected to a flat edge piece (304) through a lower edge piece (303). There is at least one pair of lower edge pieces (303) and flat edge pieces (304). The pair of lower edge pieces (303) and flat edge pieces (304) are symmetrical about the center of the connecting cover (301). The lower edge piece (303) passes through the through groove (202). The lower surface of the flat edge piece (304) is flush with the lower surface of the base (201). The lower surface of the flat edge piece (304) is the lower adhesive surface (306), which is suitable for adhesion and fixation to the skin of the surgical subject.
2. The surgical thoracoscopic fixation device according to claim 1, wherein: The base (201) has an extension plate (203) on its side, and the bottom surface of the extension plate (203) has a fitting groove (204) suitable for fitting with the flat edge piece (304).
3. The surgical thoracoscopic assisted fixation device of claim 2, wherein: The flat edge piece (304) located below the extension plate (203) is provided with an upper adhesive surface (305), which is suitable for bonding and fixing to the inner top surface of the fitting groove (204) of the extension plate (203).
4. The surgical thoracoscopic-assisted fixation device as described in claim 3, characterized in that: Both the upper adhesive surface (305) and the lower adhesive surface (306) are covered with plastic film before use.
5. The surgical thoracoscopic assist fixation device of claim 4, wherein: There are four through slots (202) on the base (201), and the length directions of adjacent through slots (202) are perpendicular. There are four sets of combinations of the lower edge piece (303) and the flat edge piece (304). Each set of the flat edge piece (304) and the lower edge piece (303) passes through one of the through slots (202) in the corresponding direction.
6. The surgical thoracoscopic fixation device according to claim 5, wherein: The positioning part (2) is integrally injection molded, and the upper surface of the extension plate (203) also has a friction strip (205).
7. The surgical thoracoscopic assist fixture of any one of claims 1-6, wherein: The upper surface of the base (201) has a gripping ring (206) coaxial with the insertion hole (208), the outer diameter of the gripping ring (206) being equal to the inner diameter of the insertion port (302), and is suitable for passing through the insertion port (302).
8. The surgical thoracoscopic fixation device according to claim 7, wherein: The outer side of the gripping ring (206) has a retaining ring (207), the outer diameter of which is larger than the inner diameter of the insertion port (302).
9. The surgical thoracoscopic assist fixture of any one of claims 1-6, wherein: The lower surface of the base (201) is provided with a relief groove (209) that is coaxial with and communicates with the insertion hole (208). One end of the hose (101) has an elastic ring (102) and the other end has a cone (103). The elastic ring (102) is fixedly connected in the relief groove (209).
10. The surgical thoracoscopic fixation device according to claim 9, wherein: The hose (101) is made of medical-grade silicone material, and the outer side of the hose (101) is provided with corrugated friction grooves (104).
