Description

Technical Field

[0001] The utility model relates to a shark structure microscopic instrument, belonging to the technical field of medical instruments. Background Art

[0002] Microsurgical instruments generally refer to microscissors, microneedle holders and microforceps, which are mainly used to shear tissues, clamp suture needles to suture wounds, lift and clamp tissues, etc. With the improvement of microsurgery technology, surgical operators have also put forward higher requirements for microsurgical instruments. Existing microsurgical instruments can no longer meet the surgical needs of contemporary doctors.

[0003] When doctors perform surgery, they hold the middle of the two handles with their thumb and index finger, and place the back of the handles above the base of the hand. During the operation, the instrument may need to be rotated along its length. There is no good support point on the rotating microscopic instrument, so the rotation operation is not flexible enough and the operation feels bad. Sometimes, tissues get in the way during rotation, and the hand rotates to a certain angle, but the instrument does not rotate accordingly, resulting in an unstable grip. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a shark structure microscopic instrument, which is convenient for an operator to rotate around the length direction of the instrument.

[0005] The shark structure microscopic instrument of the utility model comprises a symmetrically arranged handle, the handle comprises a gripping portion, a supporting leg and an operating portion, the gripping portion, the supporting leg and the operating portion are arranged in sequence, and a protrusion is arranged on the top of the gripping portion. The protrusion is arranged on the gripping portion to support the operator's fingers (generally the thumb and index finger), which is convenient for the operator to rotate around the length direction of the instrument.

[0006] The protrusion is arranged in an arc shape inwardly on one side close to the supporting leg, which is adapted to the outer edge shape of the user's index finger. This is more in line with the ergonomic design, and the user's index finger is semicircularly wrapped, so that the user can get a better operating feel.

[0007] The protrusion is detachably connected to the gripping portion. Protrusions of different sizes can be designed, and different operators can select protrusions of different sizes to be installed on the gripping portion according to the size of their hands.

[0008] The operating part is hinged in a scissor shape, the thickness of the tail end of the scissor blade is greater than the thickness of the top end, and the tail end of the grip is cross-set. The scissor blade is thinner near the top 1 / 3, suitable for cutting delicate tissues; the back 2 / 3 blade is thicker and has stronger rigidity, suitable for cutting calcified or harder tissues. When encountering different tissues, the corresponding blade part is selected for cutting, so as to prevent the blade from breaking when cutting harder tissues, and extend the service life of the microscissors.

[0009] The operating part is hinged in a clamp shape, and the bottom end of the gripping part is cross-arranged.

[0010] The operating part is in the shape of tweezers, and the bottom end of the holding part is parallel and fixed.

[0011] The grip and legs are made of titanium alloy, and the operating part is made of stainless steel. The density of titanium alloy is about half of that of stainless steel, and the rust resistance of titanium alloy is much greater than that of stainless steel. The different materials of the grip, legs and operating part not only ensure that the operating part has greater rigidity, greater force when shearing or clamping, smooth shearing, and firm clamping, but also reduce the overall weight of the device, so that the operator will not be easily fatigued when holding the device for a long time.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The utility model provides protrusions on the gripping portion to support the operator's fingers (generally the thumb and index finger), thereby facilitating the operator to rotate the instrument along the length direction.

[0014] (2) The protrusion is detachably connected to the grip portion. Protrusions of different sizes can be designed, and different operators can select protrusions of different sizes to be installed on the grip portion according to the size of their hands.

[0015] (3) The grip and legs are made of titanium alloy, and the operating part is made of stainless steel. The density of titanium alloy is about half of that of stainless steel, and the rust resistance of titanium alloy is much greater than that of stainless steel. The different materials of the grip, legs, and operating part not only ensure that the operating part has greater rigidity, greater force when shearing or clamping, smooth shearing, and firm clamping, but also reduce the overall weight of the instrument, so that the operator will not be easily fatigued when holding the instrument for a long time.

[0016] (4) The operating part is hinged in a scissor shape, the thickness of the tail end of the scissors blade is greater than the thickness of the top end, and the tail end of the grip is cross-set. The scissors blade is thinner near the top 1 / 3, suitable for cutting delicate tissues; the back 2 / 3 of the blade is thicker and more rigid, suitable for cutting calcified or harder tissues. When encountering different tissues, choose the corresponding blade part for cutting to prevent the blade from breaking when cutting harder tissues, thereby extending the service life of the microscissors.
