As shown in fig. 1-6, a multifunctional teaching scalpel comprises a hilt 1 and a miniature air pump 4, wherein a blade 2 is arranged at the bottom of the front end of the hilt 1, a blood exhaust channel 103 penetrating through the hilt 1 is formed at two ends of the hilt 1, a blood conveying pipe 3 is communicated between one end of the hilt 1, which is far away from the blade 2, and the blood exhaust channel 103, and a blood storage tank 5 is communicated with the air inlet end of the miniature air pump 4 and the blood storage tank 5 is also communicated with one end of the blood conveying pipe 3.

In the embodiment, a micro air pump 4 is used for generating negative pressure in a blood storage tank 5 communicated with the micro air pump, at the moment, a blood transfusion tube 3 and a blood discharge tube 103 which are communicated with the blood storage tank 5 drain the blood part of the tissue cut at the top of the knife handle 1, so that the blood flows into the blood storage tank 5 through a tube communicated with the blood storage tank 5, the blood of the tissue part of a patient is cleaned, and the operation of a doctor in an operation is facilitated; it should be noted here that the tube connecting the blood storage tank 5 and the micro air pump 4 should not extend into the bottom of the blood storage tank 5, so as to avoid the ejection of blood sucked by the micro air pump 4 through the tube.

Concretely, handle of a knife 1 includes grab handle 101 and the extension handle 102 that is located grab handle 101 front end, guide slot 104 has been seted up to the bottom of extension handle 102, grab handle 101 and extension handle 102's transition department has seted up out sword groove 105, blade 2 includes blade 201 and fixes at blade 201 top and be used for gliding guide block 202 in guide slot 104, the one end that the blade 201 kept away from the knife tip is restricted in out sword groove 105, the equal fixed mounting in both sides that blade 201 kept away from knife tip one end has push away handle 203, two push away the outside that the equal slip of handle 203 set up at handle of a knife 1.

In the embodiment, because the blood discharging channel 103 for circulating blood needs to be arranged in the knife handle 1, the specification of the knife handle 1 is larger than that of a common scalpel, in order to avoid the knife handle 1 from obstructing the operation of a doctor carrying the knife, the blade 2 is arranged to slide in a groove structure arranged on the knife handle 1, the blade 2 is retracted into the knife handle 1 during blood suction, the blade 2 is pushed out of the knife handle 1 during cutting, the push handles 203 on two sides of the knife handle 1 are arranged at the joint positions of fingers of the doctor during knife carrying, and the good comfort of the doctor during knife carrying is ensured.

Specifically, one end fixed mounting that blade 201 kept away from the knife tip has one 6 of spring and one 6 of spring to keep away from blade 201 and moves out sword groove 105 fixed connection, spout 106 and spout 106 are seted up at the top of hilt 1 and are slided in and be provided with L type piece 7, fixed mounting has two 8 of spring and two 8 of spring to keep away from the one end and the hilt 1 fixed connection of L type piece 7 on the L type piece 7, but all offer on blade 201 and the L type piece 7 mutually support gliding chamfer and the blade 201 and be used for inserting the slot 204 of establishing L type piece 7.

In this embodiment, the scheme is when adopting the mode optimization operation of propelling movement blade 2, and in order to guarantee that equipment blade 2 is difficult for following handle of a knife 1 landing when blood sucking, but set up L type piece 7 receive under the effect of spring two 8 can the joint in the slot 204 of seting up on blade 201, and the concrete mode of manifesting is: when the knife body 201 retracts into the knife withdrawal groove 105, chamfers on the knife body 201 and the L-shaped block 7 are matched with each other, the L-shaped block 7 is driven to ascend in the sliding groove 106 by the aid of force application extrusion at the chamfers, the knife body 201 continues to retreat when the L-shaped block 7 moves to the top of the knife body 201 until the L-shaped block 7 is clamped in the inserting groove 204 under the action of the second spring 8, the knife blade 2 is driven to be limited at a fixed position on the knife handle 1, extra force can be additionally applied to the knife blade 2 by the aid of the first spring 6, force applied to the knife blade 2 is prevented from being concentrated on fingers, and good operation stability of the knife blade 2 is guaranteed.

Specifically, the L-shaped block 7 is provided with an opening and closing hole 12 for opening and closing the exhaust duct 103.

In the embodiment, considering that when blood suction is not needed to be performed on the tissue of a patient, in order to avoid the influence caused by the action of the miniature air pump 4, the on-off hole 12 can be formed in the L-shaped block 7, when the blade 2 is retracted, the L-shaped block 7 rises, at the moment, the on-off hole 12 is communicated with the blood discharge channel 103, the suction action of the miniature air pump 4 can be started, when the blade 2 is needed, the L-shaped block 7 is lifted up, the blade 2 moves forwards under the action of the first spring 6, the L-shaped block 7 drives the on-off hole 12 to move downwards under the action of the second spring 8, the on-off hole 12 and the blood discharge channel 103 deviate from each other, the blood suction action of the device is closed, due to the negative pressure action inside the blood discharge channel 103, excessive blood in the blood discharge channel 103 cannot flow out, and.

Specifically, the outside fixed mounting of L type piece 7 has the flange, and the top fixed mounting of hilt 1 has articulated seat 9, and the internal rotation of articulated seat 9 is provided with V template 10, and the bottom fixed mounting that the one end setting of V template 10 was in the bottom of flange and the V template 10 other end has three springs 11, and the one end and the hilt 1 fixed connection of V template 10 are kept away from to three springs 11.

In this embodiment, in order to lift L type piece 7, set up V template 10 and change the chimb department that the action was used in L type piece 7, finger extrusion spring three 11 drives V template 10 another side lifting, has avoided the mode that need extract with the hand with the mode of pressing, more is favorable to doctor's operation.
