Description
Technical field
This utility model is related to the technical field of medical apparatus and instruments, more particularly to the technology of operation medical apparatus and instruments
Field.
Background technology
In recent years, with the rising of pregnant and lying-in women's Cesarean esction ratio, gestation person is also therewith again for cesarean postoperate uterine cicatrix
Increase, if the uterine cicatrix of parturient after undergoing caesarean section is pregnant again, i.e., uterine cicatrix labor induction when its difficulty and risk it is more non-
Substantially increase in operation uterus.Conventional termination of pregnancy method is divided into two methods of operative treatment and expectant treatment, wherein handss at present
Art Therapeutic Method it is relatively costly, intraoperative blood loss is relatively more, and patient trauma is larger；Conventional expectant treatment method has at present
After the treatment of the PTCA or and STENTS clearing heat in the pericardium, Drug therapy, uterine curettage, traditional uterine cavity local puncture medication and add three kinds of methods of uterine curettage.Intervention
Treatment plus Drug therapy are, by blood vessel embolism, to block the blood supply of gestation by interventional therapy, then inject medicine by embryo
The clearing heat in the pericardium after kill, the method treatment success rate are high, but hospitalization cost is high, and the only expense of interventional therapy can nearly ten thousand yuan.Drug therapy
Plus uterine curettage uses chemotherapeutics（MTX）The clearing heat in the pericardium after kill by embryo, the method treatment time are long, success rate
Low, side effect is on the high side.It is the clearing heat in the pericardium after tradition punctures medication that traditional uterine cavity local puncture medication to add uterine curettage, and the method no matter
Trans-abdominal portion punctures or uterine cavity is punctured, and easily punctures blood vessel, cause big when all causing and puncture because of the intensive complexity of blood vessel at cicatrix gestation
Bleeding, causes expectant treatment failure and uses operative treatment instead.Therefore three of the above method has weak point, so exploitation should be inquired into
New Therapeutic Method improves expectant treatment success rate, saves subjects reproductive's function from damage to reduce massive hemorrhage rate, reduce wound, improves
Quality of life.
Utility model content
The purpose of this utility model is exactly to provide a kind of simple structure to solve above-mentioned deficiency, reasonable in design, can
Massive hemorrhage rate during uterine cicatrix labor induction is substantially reduced, and can effectively reduce the sleeve pipe pullover of operation risk and medical treatment cost
Puncture needle.
The technical solution that this utility model is adopted to solve above-mentioned technical problem is as follows：
Sleeve pipe pullover puncture needle, it includes the trocar and sleeve pipe nook closing member, and the nook closing member activity of described sleeve pipe nook closing member is plugged on
In the needle tubing of the trocar, it also includes sheath, and the sheath activity is nested with outside the needle tubing of the trocar, in the front end of the sheath
Sidepiece offers inserting needle mouth, the front end of described sleeve pipe pin and the front end flush of sleeve pipe nook closing member, the length of described sleeve pipe pin needle tubing
3 ~ 5cm longer than the length of sheath.
The sheath is silica gel material.
The opening direction of the inserting needle mouth of the sheath is oblique top.
The needle tubing length of described sleeve pipe pin is 16cm, and the length of sheath is 12cm, the inserting needle mouth distance from bottom sheath of sheath
The vertical dimension on top is 1.5cm.
The bottom of described sleeve pipe nook closing member is provided with positive stop lug boss, and described sleeve pipe pin bottom offers spacing with sleeve pipe nook closing member
The corresponding groove of boss, the positive stop lug boss holding of sleeve pipe nook closing member is in the groove of trocar bottom.
The technical solution of the utility model is summed up in practice, and which is reasonable in design, not only it is simple and easy to do but also safety can
Lean on.The sleeve pipe pullover puncture needle is equipped with sheath in the trocar sleeve of traditional puncture needle, when in use, first by sheath from patient's
Vagina sends into uterine cavity, after the direction that guard leading end complies with uterine cavity reaches amniotic cavity, by the trocar and sleeve pipe nook closing member insertion sheath
It is interior, then the front end of the trocar is passed from the inserting needle mouth of sheath, punctured to amniotic cavity and pushed pin the injection medicine that draws water, from
And avoid when puncture needle is walked from the cicatrix of uterine cicatrix gestation and puncture blood vessel.Can be reached using above-mentioned technical solution
To beneficial effect be：Massive hemorrhage rate is effectively reduced, the risk of uterine cicatrix labor induction is greatly reduced, is effectively increased
The success rate of expectant treatment, while it also avoid carrying out induced labor using operation method, effectively reduces treatment cost, has saved trouble from damage
The reproductive function of person, improves the quality of life of patient.
