Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, and specifically is a tonsil grabbing forceps. BACKGROUND

[0002] The palatine tonsil is also called tonsil, which is located in the triangular tonsil fossa surrounded by the palatoglossal arch and the palatopharyngeal arch. With the growth of age, the immune function of children's tonsils gradually becomes active, especially when the children are 3-5 years old, the chance of contacting allergens increases, and the tonsils significantly increase. At this time, the tonsil hypertrophy should be considered as a normal physiological phenomenon. However, the excessive hypertrophy of the tonsil will lead to respiratory obstruction in children, and even hypoxemia in severe cases. Long-term hypoxemia will significantly affect the physical and intellectual development of children. The most commonly used traditional surgical method for removing tonsils in children includes tonsil dissection and extrusion incision. When the tonsil is surgically removed, the tonsil is first grabbed by a grabbing forceps, and then a plasma knife is used for surgery. The prior art 201320038860.5 discloses a novel tonsil clamping forceps, which comprises two mutually hinged handles and a clamp mouth provided on the handles. A plurality of light source supports are arranged on one of the handles at intervals. The light source supports are fixedly connected or detachably connected with the handle. Although the tonsil surgery is more intuitive, safe, convenient, and comfortable due to the pulling and light exposure functions, the uvula may be accidentally injured when the plasma knife is used for some patients with abnormally enlarged tonsils or thickened uvula. SUMMARY

[0003] The utility model aims at solving the above problems, and provides a tonsil grabbing forceps capable of preventing the uvula from being accidentally injured.

[0004] The utility model solves the problem by adopting the technical scheme of:

[0005] The utility model discloses a tonsil grabbing forceps, which comprises two hinged forceps handles, the front end of the forceps handle is provided with a curved forceps mouth, the end of the forceps handle is provided with a handle, and a fixing mechanism is connected and fixed at the middle part of the handle body on the back arc side of the forceps mouth. A shielding plate extending towards the front end of the forceps handle is arranged on the surface of the fixing mechanism away from the forceps handle, and the shielding plate is used for isolating the uvula and the tonsil.

[0006] Compared with the prior art, the utility model has the following outstanding features:

[0007] The fixing mechanism is fixed on the forceps handle, and the angle of the fixing mechanism remains unchanged on the center line of the opening when the forceps handle is opened or closed. The shielding plate is located on the back arc side of the forceps mouth. When the grabbing forceps is used, the shielding plate blocks the uvula outside the grabbing forceps, thereby preventing the uvula from being accidentally injured by the plasma knife.

[0008] As a preferred embodiment, the utility model further has the following technical scheme:

[0009] Further, the fixing mechanism comprises a fixing plate, one side of the fixing plate is hinged with the pin shaft between the two handles, one side of the fixing plate is close to the handle and is provided with a long strip-shaped movable hole, a clamping block is slidably clamped in the movable hole, and the side of the clamping block facing the handle is symmetrically hinged with a supporting rod between the two handles.

[0010] Further, one end of the shielding plate away from the mouth of the forceps is hinged with the middle part of the fixing plate, and a reset spring is arranged between the middle part of the shielding plate and the fixing plate.

[0011] Further, the width of the shielding plate close to the mouth of the forceps is greater than the width of the other side.

[0012] Further, the two handles are provided with toothed clamping plates at the opposite ends. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is a three-dimensional structure schematic diagram of the embodiment of the utility model;

[0014] Figure 2 It is a front view structure schematic diagram of the embodiment of the utility model;

[0015] In the drawing, the marks are: handle 1, mouth 2, handle 3, shielding plate 4, fixing plate 5, movable hole 51, clamping block 52, supporting rod 6, reset spring 7, clamping plate 8. DETAILED DESCRIPTION
