Description
Technical field
It is specifically a kind of to be used for tumor of breast Minimally Invasive Surgery the present invention relates to tumor of breast Minimally Invasive Surgery equipment technical field
Suction type biopsy sampler.
Background technique
Minimally Invasive Surgery has that wound is small, pain is light, restore fast, that the hospital stays is short, bleeding is few is excellent relative to traditional operation
Point is now widely used for treating in various diseases.It in the preoperative and postoperative of tumor of breast, needs to sample biopsy, using as disease
Manage the important evidence of diagnosis.
A kind of visceral layer biopsy needle is disclosed application No. is 201010214740.7 patent of invention, including needle tubing and interior is placed on
Inner sleeve in needle tubing, the inner surface of needle tubing and the outer surface of inner sleeve are respectively arranged with mutually matched internal screw thread and outer spiral shell
Line is additionally provided with piston in inner sleeve and connects the piston rod of piston, is additionally provided with through-hole along axial direction in the tube wall of inner sleeve, leads to
Sampling cutter control-rod is provided in hole, sampling cutter control-rod is fixedly connected with crescent sampling cutter, crescent close to needle point one end
Sampling cutter can be rotatably set in inner sleeve on the annular tube wall of needle point one end.When using the visceral layer biopsy needle, by needle tubing
It is inserted into the patient, it pulls piston rod by organs and tissues negative suction room, then rotates sampling cutter control-rod and sampling cutter is driven to exist
The front end face of inner sleeve rotates, and organs and tissues are cut off.The visceral layer biopsy needle has the disadvantage in that (1) draws organs and tissues
When, a hand grasps needle tubing, and another pulls piston rod of starting and draws to organs and tissues；When cutting off organs and tissues, one
Hand grasps needle tubing, and another hand rotates sampling cutter control-rod, it is seen then that needs medical worker's both hands to operate the visceral layer biopsy needle, grasps
It is inconvenient to make；(2) pivoting point of crescent sampling cutter and inner sleeve is in the position far from inner sleeve axle center, so that crescent sampling cutter
Rotational trajectory can cover the port of inner sleeve, area coverage when this causes crescent sampling cutter to rotate is larger, can be to trouble
The organs and tissues of person cause additional damage.
Summary of the invention
The purpose of the present invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of for tumor of breast Minimally Invasive Surgery

The suction type biopsy sampler of art, including probe tube, sampling cutter, shaft, screw rod, nut, nut drive rod, the first spring, company
Connect bend pipe, negative pressure cylinder, piston and second spring；The lower end of the probe tube is equipped with sampling room, and the cross section of the sampling room is in
Circle, the upper end closed and lower ending opening of the sampling room；The sampling cutter is fixedly connected with shaft, and the shaft is rotatable
Be mounted on probe tube and it is coaxial with sampling room, the sampling cutter is located in sampling room；The screw rod and shaft are coaxially solid
Fixed connection, the nut and screw rod cooperate, and the nut drive rod can slide up and down with probe tube to be connect and fix with nut
Connection, first spring are set between nut drive rod and probe tube；The side of the probe tube is by bridge piece and bears
Pressure cylinder is fixedly connected, and the sampling room is connected to by bridge piece with negative pressure cylinder；The piston is matched and is mounted on negative pressure cylinder
In negative pressure cylinder, the second spring is located between piston and negative pressure cylinder.
Technical solution of the present invention is also: the junction of the shaft and probe tube is equipped with rotatory sealing, makes shaft and takes
The junction of sample pipe seals.
Technical solution of the present invention is also: the axis of the negative pressure cylinder and the axis of sampling room are parallel.
Technical solution of the present invention is also: further including connector sleeve, the connector sleeve fixation is set in probe tube and negative pressure cylinder
Outside.Using the technical program, connector sleeve can increase the connection rigidity of probe tube and negative pressure cylinder, prevent bridge piece from damaging
It is bad, additionally it is possible to increase comfort when medical worker holds sampler.
Technical solution of the present invention is also: the nut drive rod and probe tube loose key cooperate, and make nut drive rod and take
It can be relatively unrotatable with respect to slide up and down between sample pipe.
Technical solution of the present invention is also: the length of the sampling cutter and the cross-sectional diameter of sampling room are equal.
In use, medical worker holds the suction type biopsy sampler for tumor of breast Minimally Invasive Surgery of the invention, use
Then thumb press piston unclamps thumb, in second spring then by the tumor of breast lesion tissue of probe tube insertion patient
Under the action of, negative pressure is generated in negative pressure cylinder, pathological tissues are attracted in probe tube, last push nut drive rod, and spiral shell is driven
Parent phase moves axially screw rod, and nut drives screw rod rotation, and screw rod drives sampling cutter rotation to cut off pathological tissues.
Compared with the existing technology, beneficial effect of the present invention for the suction type biopsy sampler of tumor of breast Minimally Invasive Surgery
Are as follows: (1) pathological tissues traction and cutting can be realized in the pressing of medical worker's one hand, and another hand can carry out other behaviour such as stop blooding
Make, saves manpower；Moreover, simplifying sampling procedure, sampling efficiency is improved；(2) sampling cutter be located in sampling room and its
Rotation center is coaxial with sampling room, not only can guarantee that sampling cutter cuts off pathological tissues, but also can prevent from causing the organs and tissues of patient
Additional damage.
