Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the utility model is divided into three components: tweezers holding end 1, traction band 2 and hole towel clamp 3. As shown in fig. 2, the forceps holding ends are divided into a forceps head 11, a forceps body 12, and a forceps tail 13. The inner side of the forceps head 11 is provided with saw-toothed projections which are mutually occluded to clamp the valve. The outer side of the forceps body part 12 is provided with anti-slip lines, the inner side of one forceps leg close to the forceps head part 11 is provided with a mushroom-shaped bulge 121, the inner side of the other forceps leg corresponding to the mushroom-shaped bulge is provided with a through hole, and the hole diameter is slightly smaller than the maximum diameter of the umbrella-shaped outer edge of the mushroom-shaped bulge 121, so that a snap fastener structure is formed. The tail 13 of the tweezers is provided with a square hole 131. As shown in fig. 3, when the saw-toothed structures of the tweezer heads 11 are engaged with each other, the snap fasteners 121 of the tweezer bodies are pressed, and the mushroom-shaped protrusions 121 are snapped into the holes, so that the fixed tissue is not loosened. As shown in fig. 4, a self-locking fixing buckle 21 is arranged at one end of the traction belt, a strip belt 22 is arranged at one side, and a stepped clamping groove bulge is arranged on the traction belt, so that unidirectional sliding and fixing are facilitated. As shown in fig. 5, a fixing needle 31 made of a stainless steel round needle is embedded in one side of the occlusion end of the orifice towel clip 3, and the other end is provided with a corresponding groove.

As shown in fig. 11, before the operation is started, the hole towel is fixed on the face and the chest of the patient by using the hole towel tying band. After the periodontal tissue valve is lifted, the forceps head 11 at the forceps holding end is used for holding the periodontal tissue valve, and the snap fastener structure of the forceps body 12 is pressed, so that the tissue does not slip off and is stably held. The strip-shaped belt 22 of the traction belt 2 is inserted into the square hole 131 of the tail part 13 of the tweezers, and the loop is inserted through the self-locking fixing buckle 21 to adjust the length to a proper position. The hole towel clamp 3 passes through and pulls the traction belt ring, the position is adjusted for the second time to ensure that the operation area is fully exposed, and then the fixing needle 31 passes through the hole towel fiber and is occluded and fixed with the groove at the other end.

The head shape of the forceps at the forceps holding end is selected from fig. 6-10 according to the type, size and position of different periodontal tissue valves. The general type A is suitable for the most common full-thickness flap tissue flap of two or three tooth positions; the thick and big tissue valves of a plurality of tooth positions can be wide flat heads C or ring-shaped E; the half-thick valve with thin and small single tooth can be a pointed head type B; the tissue flap on the palate side can be a bent sharp head type D, so that the tissue flap can conveniently straddle the hard tissue of the tooth body. According to the range size and individual difference of the tissue flap, forceps clamping ends with different lengths (5-15 mm) of the forceps head 11 can be selected.

The utility model discloses can select a plurality of single or more tweezers exposed core to merge single or a plurality of traction band ring according to clinical situation, choose for use one or more hole towel presss from both sides and adjust tractive and fixed direction wantonly, the individuation exposes art district. The operation is flexible and simple, the operation wound is reduced, the hands of a nurse are thoroughly liberated, the convenience of the operation is improved, and the operation time is shortened.

After the operation main body step is finished, the snap fastener structure of the forceps body part 12 can be broken off with slight force, if the force of an operator is extremely small or the hand is slippery, the operator can cut off the forceps body part by using crown scissors or cut off the forceps body part by using an electric knife, and then the whole drag hook can be completely disassembled by opening the hole towel clamp 3.

The three components of the utility model can be separated and can be used independently, for example, the clamping end of the pointed B-shaped tweezers can also be applied to the separation between the periodontal tissue multilayer structures; the traction belt 2 can be used for binding objects; the hole towel clip 3 can also be used for fixing other medical articles and the like, thereby greatly expanding the clinical practicability.

The utility model discloses a resin material that three component part adopts biological high safety performance, and the fixed needle of hole piece of cloth clamp can adopt stainless steel round needle, and equal disposable accords with aseptic principle, and the environmental protection is nontoxic.

It should be noted that the present invention introduces two features of "softness". The square metal drag hook shape of traditional type of comparing is fixed, the texture is hard, non-deformable, use easy slippage, so need nursing staff complex characteristics, the utility model discloses a simple and easy "equipment" soft design theory, freely splice, control tensile position and angle to chooseed for use the "soft" material of resin material, made action such as concatenation, snap-fastener, take off effectively to carry out fast, ensured the environmental protection nontoxic simultaneously again.
