Embodiment 1

[0033] Such as figure 1 , Figure 4 , Figure 7 A suction head with adjustable stripping function is shown, including a tailstock 1, four inner cores 3, an outer sheath 2, a suction control assembly 5 and two sets of adjustment assemblies 4. The tailstock 1 consists of a seat body 11 and a cover Body 12 is assembled, and a back-shaped groove 14 and two clamping chambers 13 are formed between the seat body 11 and the cover body 12. connected, and the tailstock 1 is provided with a main suction hole 113 communicating with the suction pipe, the seat body 11 is provided with a core rod part 111 extending forward, and four core rod parts 111 are provided in the core rod part 111 to communicate with the main suction hole 113. The four communicating holes 1111 all pass through the front end surface of the core rod part 111, and the four inner cores 3 are connected to the four communicating holes 1111 one by one. The inner core 3 is made of a memory metal material, and the inner cor...

Embodiment 2

[0042] Such as Figure 8 As shown, on the basis of Embodiment 1, the front end of the inner core 3 is provided with a ball head 32, which increases the contact area between the inner core 3 and the tumor, and prevents the inner core 3 from piercing the tumor. The surface of the part 32 is provided with several branch suction holes 321, and the branch suction holes 321 communicate with the suction channel 31, and the setting of the branch suction holes 321 makes the suction effect of the inner core 3 better.

Embodiment 3

[0044] Such as Figure 9 As shown, on the basis of Embodiment 1, an elastic connecting body 7 is connected between two adjacent inner cores 3 and the front end of the elastic connecting body 7 is flush with the front end of the inner core 3, and the elastic connecting body 7 is made of high elasticity. Made of rubber material, the elastic connecting body 7 is fixed on the inner core 3 by adhesive, when the four inner cores 3 are opened in a fan shape, the elastic connecting body 7 is stretched, and the setting of the elastic connecting body 7 increases the internal The contact area between the core 3 and the tumor prevents the inner core 3 from piercing the tumor.

[0045] preferred, such as Figure 10 As shown, the front end of the elastic connecting body 7 is provided with a cylindrical portion 71 .

Abstract

The invention provides an aspirator head with an adjustable stripping function, comprising: a tailstock, the tail of which is connected to a suction pipe, and a main suction hole communicating with the suction pipe is arranged in the tailstock; core, the inner core is provided with a suction channel, and several inner cores are connected to the front end of the tailstock, and the suction channel communicates with the main suction hole; the outer sheath, the outer sheath is set outside the inner core, and the outer sheath is flexibly connected to the On the tailstock, when the outer sheath moves backward, the front ends of several inner cores are exposed and opened in a fan shape; the adjustment component is arranged on the tailstock, and the adjustment component is used to control the front and rear movement of the outer sheath; the suction control component is the suction control The component is arranged on the tailstock, and the suction control component is used to control whether the suction channel communicates with the suction pipe. The suction head with adjustable peeling function provided by the present invention can adjust the size of the peeling area according to the needs of the operation while having the suction function.

Description

technical field [0001] The invention relates to an aspirator head, in particular to an aspirator head with an adjustable stripping function. Background technique [0002] Aspirator is a commonly used surgical instrument in shell surgery, which is used to suck blood and other fluids during surgery to keep the surgical field of view clear. At present, the common aspirator on the market is a hollow tube, and the basal part will bleed when the tumor is peeled off. If the ordinary aspirator is used to attract and peel off the tumor at the same time, the pressure at the peeling point is high and the tumor is easy to break. [0003] To sum up, how to avoid the occurrence of the above situation is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide an aspirator head with an adjustable peeling function, which solves the problem that the tumor is easily broken when the pressure at the peel...
