Pressing type adsorbing machine for adsorbing human tissue

Abstract

The invention discloses a pressing type adsorbing machine for adsorbing human tissue. The pressing type adsorbing machine comprises an air cylinder, a piston assembly and a one-way valve cushion, wherein the air cylinder comprises a piston operating cavity, a valve cavity and a connecting pipe; the piston operating cavity, the valve cavity and the connecting pipe are in mutual communication; the piston assembly is arranged in the piston operating cavity in an axial direction in a sliding manner; a pressing strip is arranged in the valve cavity, and is used for fixing the one-way valve cushionto a connecting pipe inlet in the bottom surface of the valve cavity; the piston assembly comprises a piston rod, a piston head and piston bodies; the center of the piston rod penetrates in the axialdirection to form a gas channel; the piston head is connected to the lower end of the piston rod; an access which communicates with the gas channel is formed in the center of the piston head; each piston body is arranged in a corresponding piston mounting part, between the piston rod and the piston head, in a sleeving manner; the lower end surfaces of the piston bodies are overlapped to the top end of the piston head; a non-return valve is arranged at a position of the access, on the upper end surface of the piston head; an adsorption head is arranged at the lower end of the connecting pipe ofthe air cylinder; and an actuator which cooperates with a driven piece is arranged at the bottom of the piston head, so that tissue is not damaged.

Description

technical field [0001] The invention relates to the technical field of medical equipment application, in particular to a press-type absorber for absorbing human tissue. Background technique [0002] With the development of science and the improvement of living standards, people pay more and more attention to their own appearance, especially in terms of skin, and pay more and more attention to the beauty effect, so medical operations are gradually becoming more refined. [0003] In surgical operations in hospitals, such as skin grafting in hospitals, skin grafting is mainly used to repair various wounds (such as burns, wounds caused by trauma, and secondary wounds after scar removal, etc.), and is widely used in clinical practice. [0004] Depending on the location and size of the wound, different skin donor sites are selected. For the sake of aesthetics, the skin donor sites are often selected in areas with loose and hidden skin, such as the groin, the inner side of the uppe...

Problems solved by technology

[0008] In the prior art, tweezers are generally used to move the skin, but the existing tweezers, when moving the skin, need to press down on the skin first and then give the skin a clamping force, the skin between the two tweezers The piece will bulge in the middle and be held by the tweezers, but this operation will cause the skin piece to be uneven. At the same time, when the existing tweezers clamp some skin tissue, because the force control is not accurate, the clamping part of the tweezers will cause the skin tissue to rupture. , is not conducive to the healing of the skin graft, and affects the appearance of the skin in the later stage

[0009] In the surgical operation of the hospital, such as the resection of the tumor in the hospital, the blood vessel forceps are usually used to lift the tumor in order to achieve the purpose of removing the tumor in the surgical treatment. When the clamp opens the opening, it takes up a lot of space, and the clamp is easy to cause tissue damage. At the same time, the extrusion of the tumor body is easy to cause tumor rupture, which increases the chance of malignant tumor metastasis and brings unnecessary pain and heavy pain to the patient. economic burden
