Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable suspension structure. Background Art

[0002] Laparoscopic surgery uses the body's natural cavities (such as the abdominal cavity, thoracic cavity, etc.) or enters the body through a small surgical incision to diagnose and treat diseases. It has the advantages of definite efficacy, minimal trauma, and quick recovery. The current laparoscopic thyroid surgery is to make a small incision in the patient's mouth or armpit, and then use a retractor to insert through the surgical incision and extend into the patient's neck. The retractor is used to pull up the anterior cervical muscles in front of the thyroid gland to ensure the surgical field of view.

[0003] The traditional method of traction hook is to use a bandage / gauze to suspend the hook on the fixed rod above the operating table, and then clamp the two ends of the bandage / gauze with a hemostat. The traditional traction method will cause waste of bandages / gauze on the one hand, and on the other hand, long-term clamping and fixing with hemostat will easily damage the hemostat. At the same time, because the traction height needs to be adjusted many times during the operation, each adjustment requires holding the bandage / gauze first, then loosening the hemostat, adjusting to the appropriate height, and clamping the bandage / gauze again. The operation process is cumbersome, so an adjustable suspension structure for hanging the hook is proposed. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model aims to provide an adjustable suspension structure to facilitate adjusting the traction height of the drag hook.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An adjustable suspension structure comprises an adjusting member, on which a traction rope is arranged, and two through holes are formed on the adjusting member. After the traction rope passes through the two through holes in sequence, its free end is connected with a draw hook. The traction rope portion between the connection point on the adjusting member and the first through hole passed through is a suspension section, and the traction rope portion between the two through holes is a locking section, which is used to lock the traction rope.

[0007] Principle of the utility model:

[0008] The suspension section in this solution is connected to the fixed rod above the operating table, and the free end of the traction rope is connected to the retractor. When in use, the retractor pulls up the anterior cervical muscles to generate a downward pulling force on the traction rope, so that the traction rope is always kept taut. When the traction rope is tensioned, the traction rope will be bent at the two through holes, and the locking section will be tightened on the surface of the adjustment member. Friction will be generated at the bending part of the traction rope and between the locking section and the surface of the adjustment member. The traction rope can avoid loosening under the constraint of friction. Therefore, in the tensioned state, the adjustment member and the traction rope will form a self-locking.

[0009] If you need to adjust the traction height, that is, adjust the length of the traction rope, you can hold the adjustment piece and slide the adjustment piece along the direction of the traction rope through external force. After reaching the required length, release the adjustment piece and the traction rope will self-lock under the action of friction.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] To adjust the traction height using this solution, one only needs to hold the adjusting piece and slide the adjusting piece along the direction of the traction rope to the desired length through external force. Compared with the traditional traction method, this solution not only replaces suspension tools such as bandages / gauze and hemostatic forceps, thus avoiding the waste of medical resources, but also after being adjusted to the appropriate height, the adjusting piece and the traction rope can be self-locking, without the need to operate the locking structure for locking. The operation is simple and convenient, and the practicability is strong.

[0012] As a preferred embodiment of the utility model, the surface of the adjusting member is evenly distributed with a plurality of protrusions between the two through holes. The protrusions provided in this solution can increase the friction between the locking section and the adjusting member, making the traction rope more stable when locked.

[0013] As a preferred embodiment of the utility model, the centers and connection points of the two through holes are connected in sequence to form a triangle. When adjusting the length of the traction rope, according to this solution, hold the adjusting member and adjust the angle of the adjusting member so that the direction of the center line from the first through hole to the second through hole is in the same direction as the pulling direction. At this time, the two through holes and the suspension point of the traction rope are in a collinear line, and the traction rope is in a vertical state, which is convenient for the adjusting member to slide and adjust the length. After adjusting to the required length, adjust the angle of the adjusting member again so that the center line of the two through holes forms an angle with the extension line of the pulling direction. At this time, the locking section of the traction rope, the extension line of the pulling direction, and the suspension point and the suspension section of the first through hole formed a triangular structure, and a triangular structure is also formed between the locking section of the traction rope and the adjusting member. According to the triangle stability principle, after adjusting the angle of the adjusting member, the multiple triangular structures formed can further improve the stability of the traction rope when locked.

[0014] As a preferred embodiment of the utility model, the suspension section is provided with a mounting piece that is detachably connected to the fixed rod above the operating table, and a pulley is provided on the mounting piece, and the suspension section moves on the pulley. In this solution, the suspension section is connected to the fixed rod through the mounting piece, and the mounting piece can position the suspension section at a fixed position on the fixed rod, avoiding the suspension section from being directly suspended on the fixed rod, and the suspension section moving left and right on the fixed rod, resulting in poor stability during the traction process; the pulley is provided on the mounting piece, and the pulley can ensure that the traction rope can move smoothly.

[0015] As a preferred embodiment of the utility model, a mounting groove is provided on the lower side of the mounting member, the fixing rod is inserted into the mounting groove, and a fixing bolt is threadedly connected to one side of the mounting groove, and the fixing bolt is used to lock the fixing rod. When using this solution, after the fixing rod is inserted into the mounting groove, the fixing bolt is pressed against the side wall of the fixing rod to lock the fixing rod, and the locking method is simple and convenient.

[0016] As a preferred embodiment of the utility model, a limiter is provided above the pulley to limit the traction rope from escaping from the pulley. In this solution, the traction rope moves on the pulley, and by providing a limiter above the pulley, the traction rope can be limited from escaping from above the pulley, thereby ensuring the stability of the traction rope movement.

DETAILED DESCRIPTION

[0023] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0025] See also Figure 1As shown, this embodiment discloses an adjustable suspension structure, including an adjusting member 1, on which a traction rope 2 is fixed. In other embodiments, a mounting hole is provided on the adjusting member 1, and one end of the traction rope 2 is tied in the mounting hole. Two through holes 11 are provided on the adjusting member 1, and the free end of the traction rope 2 passes through the two through holes 11 in sequence and is connected to the retractor, wherein the portion of the traction rope 2 between the connection point 12 on the adjusting member 1 and the first through hole 11 passed through is a suspension section 21, and the suspension section 21 is suspended on the fixed rod 4 above the operating table, and the portion of the traction rope 2 between the two through holes 11 is a locking section 22, and the locking section 22 is used to lock the traction rope 2. When the present solution is in use, the retractor pulls up the anterior cervical muscles, generating a downward pulling force on the traction rope 2, so that the traction rope 2 is always kept taut. When the traction rope 2 is tensioned, the traction rope 2 will be bent at the two through holes 11, and the locking section 22 will be stretched tight on the surface of the adjusting member 1. Friction will be generated at the bending part of the traction rope 2 and between the locking section 22 and the surface of the adjusting member 1. The traction rope 2 can be prevented from loosening under the constraint of friction, thereby locking the traction rope 2.

[0026] Furthermore, the suspension section 21 is provided with a mounting member 3, and the suspension section 21 is connected to the fixing rod 4 above the operating table through the mounting member 3. For details, see Figure 4 As shown, a mounting groove 31 is formed on the lower side of the mounting member 3, and the fixing rod 4 is inserted into the mounting groove 31. A fixing bolt 311 is threadedly connected to one side of the mounting groove 31. When using this solution, after the fixing rod 4 is inserted into the mounting groove 31, the fixing bolt 311 is screwed so that the fixing bolt 311 is pressed against the side wall of the fixing rod 4, and the mounting member 3 can be fixed on the fixing rod 4. A pulley 33 is installed on the upper side of the mounting member 3, and the suspension section 21 moves on the pulley 33. A limiting member 32 is provided above the pulley 33 for limiting the traction rope 2 from escaping from the pulley 33. The limiting member 32 is in an inverted U shape, and one end of the limiting member 32 is hinged to the mounting member 3. A slot 321 is provided at the other end of the limiting rod. A block 34 is integrally formed on the mounting member 3 to cooperate with the slot 321. When the suspension section 21 moves on the pulley 33, the slot 321 and the block 34 cooperate, and the limiting member 32 can limit the traction rope 2 from escaping from above the pulley 33, thereby ensuring the stability of the movement of the traction rope 2.

[0027] Furthermore, a plurality of protrusions 13 are evenly distributed on the surface of the adjusting member 1 and located between the two through holes 11. The protrusions 13 are made of rubber. By providing the protrusions 13, the friction between the locking section 22 and the adjusting member 1 can be increased, and the stability of the traction rope 2 when locked can be improved.

[0028] Furthermore, the centers of the two through holes 11 and the connection points 12 are connected in sequence to form a triangle. When using this solution to adjust the length of the traction rope 2, hold the adjustment member 1 and adjust the angle of the adjustment member 1 so that the direction of the center line from the first through hole 11 to the second through hole 11 is in the same direction as the pulling direction. Figure 3 As shown, at this time, the two through holes 11 and the suspension point 211 of the traction rope 2 are in a collinear line, and the traction rope 2 is in a vertical state, which facilitates the sliding of the adjustment member 1 and the adjustment of the length. When the desired length is adjusted, the angle of the adjustment member 1 is adjusted again so that the center line of the two through holes 11 forms an angle with the extension line of the pulling direction, see Figure 4 As shown, at this time, the locking section 22 of the traction rope 2, the extension line of the pulling direction, and the suspension point 211 form a triangular structure with the suspension section 21 part of the first through hole 11 passed through. A triangular structure is also formed between the locking section 22 of the traction rope 2 and the adjusting member 1. According to the triangle stability principle, by adjusting the angle of the adjusting member 1, the multiple triangular structures formed can further improve the stability of the traction rope 2 when locked.

[0029] Specific implementation process:

[0030] After the mounting member 3 is fixed on the fixing rod 4, the hanging section 21 of the traction rope 2 is placed on the pulley 33, and the free end of the traction rope 2 is connected to the hook. If the traction height needs to be adjusted, hold the adjusting member 1 by hand, adjust the angle of the adjusting member 1, so that the direction of the center line from the first through hole 11 to the second through hole 11 is in the same direction as the pulling force direction, and then slide the adjusting member 1 along the direction of the traction rope 2 by external force. After reaching the required length, release the adjusting member 1, and adjust the angle of the adjusting member 1 again, so that the center line of the two through holes 11 forms an angle with the extension line of the pulling force direction. At this time, the traction rope 2 will be self-locking under the action of friction, and the operation is simple and convenient.

[0031] In addition to being used for suspending retractors, the adjustable suspension structure disclosed in the present solution can also be used for suspending other structures that need to be suspended in an operating room.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
