Specific embodiment
In order to make those skilled in the art that the present invention may be better understood, below with reference to embodiment to the technology of the present invention
Scheme further illustrates.
As shown in Figure 1, a kind of disposable percutaneous lung puncture biopsy by application pincers of the present embodiment, comprising: binding clip 1, clamp handle, puncture tube
2 and for controlling the curved bending control system of the puncture tube 2；The binding clip 1 includes coaxially being articulated with 2 front end of puncture tube simultaneously
Two clamps 7 of scissor structure are formed, the clamp 7 is equipped with the groove 6 for accommodating biopsy；The clamp handle includes solid
Due to 2 rear end of puncture tube fixed handle and be articulated with the movable handle of the fixed handle, the movable handle is connected with across wearing
Pierce pipe 2, and the drag-line 10 for pulling two clamps 7 to close up；In use, binding clip 1 protrudes into human body, medical worker's hand-hold pincers
Handle, thumb are inserted in the annulus of flexible handle 4, and middle finger is inserted in the annulus of fixed handle 5, then drive flexible handle 4 to fixation
Handle 5 rotates, and flexible handle 4 pulls on rope at this time, closes up two clamps 7 of binding clip 1 mutually, simultaneously by biopsy clamping
It is contained in the bowl-shape groove 6 on clamp 7, finally binding clip 1 is taken out and completes biopsy operation, after release handle, flexible handle 4 exists
It is unfolded under the action of reset spring 18, resets the separation of two clamps 7.
The puncture tube 2 includes that the segment of two mutual detachable connections (is realized two segments by sealing pipe screw thread
Connection), wherein for the tube body 8 for the Anterior Segment that the binding clip 1 connects for flexible material production, the rear segment connecting with clamp handle is doctor
It is made of stainless steel material；Since the last stage connecting with binding clip 1 can dismantle, the prosthomere can be removed after the completion of biopsy
Duan Guanti 8 is replaced, thus Anterior Segment tube body 8 be it is disposable, to substantially reduce infection risk.The institute of Anterior Segment
State elastic bar 17 and shape memory alloy spring 11 there are four being along the circumferential direction uniformly interspersed in the tube wall of tube body 8；Institute
Bending control system is stated to include for the voltage generator to a certain 11 output voltage of shape memory alloy spring and be
The battery of the voltage generator power supply；Elastic bar 17 is made by spring steel, with fabulous toughness and elasticity, four shapes
The specification of shape memory alloys spring 11 is all the same, therefore, entire soft when not being powered to shape memory alloy spring 11
Property tube body 8 under the supporting role of elastic bar 17 will keep straight (certainly, due to tube body gravity, tube body is still remained
Bending by a small margin), when needing is bent flexible pipe to a direction, voltage generator can be closed to the shape memory of the direction
Golden 11 output voltage of spring, electric current heat spring, shrink shape memory alloy spring 11, and tube wall locating for the spring is pulled to receive
Contracting, to realize the bending of flexible pipe；After stopping applying voltage, shape memory alloy spring 11 discharges, and muscle restores in elasticity,
To make flexible pipe body 8 restore straight.
The disposable percutaneous lung puncture biopsy by application of the present embodiment clamps, and further includes for accommodating the voltage generator and battery
Shell 3；The puncture tube 2 runs through the shell 3 along longitudinal direction, and fixed jacket is equipped in shell 3 in the external thread sleeve of puncture tube 2
13, and the adjustment gear 14 being arranged in a manner of axially position；The inner circle of the adjustment gear 14 is equipped with and the external screw thread
The internal screw thread of cooperation, the interior motor 16 being equipped with for driving the adjustment gear 14 to rotate of the shell 3；The inner wall shape of shell 3
At two for carrying out the barricade of axial limiting to adjustment gear 14, which should coat polytetrafluoroethylene ethylene layer, reduce itself and tooth
Take turns the frictional force between end face, when adjustment gear 14 rotates, can drive external thread sleeve 13 and 2 forward end of puncture tube stretch out or
It retracts backward, to adjust the length that entire puncture tube 2 stretches out shell 3, medical worker can adaptability according to the needs of use
The overhang of puncture tube 2 is adjusted, certainly, to avoid puncture tube 2 from rotating around its axis relative to shell 3, shell 3 and puncture tube 3
Between settable key or spline, make puncture tube be merely capable of axially with respect to shell 3 be translatable, without being able to rotate.
In the present embodiment, the puncture tube 2 is equipped with length scale ruler；Medical worker can intuitively read from graduated scale
The depth that caliper is pierced into, improves the convenient degree used.
In the present embodiment, the tube body 8 is made by silica gel, and the elastic bar 17 is embedded in advance in 8 tube wall of tube body, pipe
The installation passage for accommodating shape memory alloy spring 11 is equipped in 8 tube wall of body along longitudinal direction, shape memory alloy spring 11
Both ends are separately connected a limit buckle, and limit buckle is located at 8 rear and front end of tube body, it is ensured that can draw after marmem heat shrink
The tube wall local contraction of dynamic tube body 8 realizes bending.
In the present embodiment, the front end of the drag-line 10 is connected to a connecting seat 9, between the attachment base 9 and two clamps 7
It has been respectively articulated with a connecting rod 12, after medical worker pulls flexible handle 4, attachment base 9, the attachment base 9 will have been pulled by drag-line 10
The rotation of two clamps 7 is driven to realize clamping movement by two connecting rods 12 again.
In a preferred embodiment of the present invention, on the basis of a upper embodiment, it can set and shake on the shell 3
Bar 15, the rocking bar 15 issue pulse voltage to shape memory alloy spring 11 for controlling voltage generator, pull rocking bar 15
It can control voltage generator along the swing of front, rear, left and right four direction to be powered to four shape memory alloy springs 11 respectively,
Therefore the size of current for the sending that the amplitude of fluctuation of rocking bar 15 is used to control voltage generator can control by the rocking bar 15
The curved direction of flexible pipe body 8 and the degree of bending.
The explanation of embodiments above is merely used to help understand method and its core concept of the invention.It should refer to
It out, for those skilled in the art, without departing from the principle of the present invention, can also be to the present invention
Some improvement and modification can also be carried out, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
