This patent application discloses a kind of right angle ultrasound cutter heads, including knife handle, operating stick and cutter head, knife handle is connected with the rear end of operating stick, cutter head is connected with the front end of operating stick, the bending angle of the cutter head is 90 °, and the length of the cutter head bending part is 8mm ~ 10mm, and the cutter head is hollow structure, cutter head bending part is equipped with several and leads blood slot, several storage haemocoeles leading the connection of blood slot and being located inside cutter head.The utility model structure is simple, design is reasonable, there is very high use value in radical hysterectomy under gynecological laparoscopy, it solves and uses ultrasonic cutter head bending amplitude small at present, be not easy to the problem of separation, hemostasis in Extensive Hysterectomy art etc., while can suitably reduce operating difficulty, conversion into open surgery caused by avoiding bleeding more, reduce patient trauma, largely reduces the bleeding got through during ureter tunnel, reduce the probability of injury of ureter to a certain extent.
Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of right angle ultrasound cutter head.
Background technique
The application of ultrasound is usually by end effect or surgical instruments etc. by ultrasonic energy conversion or incoming biological tissue,
Some physiological effects are generated, tissue is carried out to burn hemostasis and cutting etc. in particular with the heat of generation.Such as surgical operation device
Tool ultrasound knife, ultrasound knife are a kind of novel operations that can have solidification and cutting function concurrently using ultrasound started the 1990s
Instrument.Ultrasound knife cutting and solidification have many advantages compared with laser and electric energy are performed the operation, for example dissection is fast, to the heat of tissue
Damage is few, generates smog in art and eschar is minimum, and wound healing is fast, and post-operation adhesion is few, is now widely used in surgical operation,
The especially Minimally Invasive Surgery of hysteroscope.
Under gynecological laparoscopy in radical hysterectomy, because range of operation will reach paracervix 3cm, ureter
It is out of shape in structure in vesico-cervical ligament section (about uterine neck by 2cm) be ureter tunnel, rete vasculosum rich in, therefore in art
Each step of separation is both needed to firm hemostasis.Ureter tunnel has certain angle, and existing ultrasonic cutter head is general because that need to be suitable for
Time surgical operation, general ultrasound cutter head, it includes knife handle, operating stick and ultrasonic cutter head, the rear end phase of knife handle and operating stick
Even, ultrasonic cutter head is connected with the front end of operating stick, and the front end of ultrasonic cutter head is bent downwardly, and crooked radian is 30 ° or so.Due to knife
Curved amplitude very little, so when separating, cutting off to ureter tunnel, it is easy to bleeding, it is inconvenient, and be easy to damage
Ureter.And the right angle forceps used in the radical hysterectomy through abdomen can handle ureter tunnel well, therefore can
Existing ultrasonic cutter head is improved to right angle cutter head, dedicated for radical hysterectomy under gynecological laparoscopy.
Utility model content
The utility model is intended to provide a kind of right angle ultrasound cutter head, to solve to be easy to damage because cutter head bending amplitude is smaller
The problem of ureter.
One of this programme right angle ultrasound cutter head, including knife handle, operating stick and cutter head, the rear end phase of knife handle and operating stick
Even, cutter head is connected with the front end of operating stick, and the bending angle of the cutter head is 90 °, and the length of the cutter head bending part is 8
~10mm, the cutter head are hollow structure, and cutter head bending part is equipped with several and leads blood slot, several described to lead the connection of blood slot and be located at
Storage haemocoele inside cutter head.
The working principle of the application is: can be very by the right angle forceps used in the radical hysterectomy through abdomen
Ureter tunnel is handled well, it is creative that existing ultrasonic cutter head is improved to right angle cutter head, dedicated under gynecological laparoscopy
Radical hysterectomy, right angle cutter head is vertical with tissue when the tissue at ureter tunnel is cut in separation, and separation is easy,
And can blood vessel in complete detachment tissue, bending part is longer compared with cutter head used in present, in separation cutting tissue, cuts
The tissue cut is relatively now using the more of cutter head, under square one, reduces so that number of operations is opposite, it is possible to reduce bleeding, behaviour
Make the reduction of number and bleeding, correspondingly just reduce the probability of damage ureter, while accelerating operation progress；Cutter head bending section
The length divided is 8~10mm.The setting of this length is the sheath card maximum diameter used generally due to present laparoscopic surgery
For 10mm, if too big can cannot be introduced into abdominal cavity, it is too small if right angle portions it is too small；Cutter head is hollow structure, cutter head bending section
It is arranged with several and leads blood slot, several storage haemocoeles leading the connection of blood slot and being located inside cutter head.Blood slot is led by setting, works as reality
When applying resection operation, a part of blood can be exported by leading blood slot, and blood slot is led in visual field when preventing Massive Bleeding from influencing excision
Interior blood can enter storage haemocoele storage.
The utility model structure is simple, and design rationally, has in radical hysterectomy very high under gynecological laparoscopy
Use value solves and uses ultrasonic cutter head bending amplitude small at present, is not easy in Extensive Hysterectomy art
In separation, hemostasis etc. problem, while can suitably reduce operating difficulty, conversion into open surgery caused by avoiding bleeding more reduce patient
Wound largely reduces the bleeding got through during ureter tunnel, reduces the several of injury of ureter to a certain extent
Rate has very high value for the doctor for begining to learn this art formula.
Further, suction tube, one end connection storage haemocoele of the suction tube, the suction tube are equipped with inside the operating stick
The other end connect negative pressure device.By being connected to the effect of the suction tube of negative pressure device, the dirt in haemocoele will can be timely stored up
Blood discharge.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of right angle ultrasound cutter head of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below by specific embodiment:
Appended drawing reference in Figure of description includes: knife handle 1, operating stick 2, negative pressure device 3, leads blood slot 4, cutter head 5.
Embodiment 1 is as shown in Fig. 1: a kind of right angle ultrasound cutter head, including knife handle 1, operating stick 2, cutter head 5 and negative pressure device
3, knife handle 1 is connected with the rear end of operating stick 2, and cutter head 5 is connected with the front end of operating stick 2, and the bending angle of cutter head 5 is 90 °, knife
The length of first 5 bending part is 8mm.
Cutter head 5 is hollow structure, and blood slot 4 is led equipped with a plurality of in 5 bending part of cutter head, and a plurality of blood slot 4 of leading is connected to positioned at knife
Storage haemocoele inside first 5 is equipped with suction tube, one end connection storage haemocoele of suction tube, the other end of suction tube inside operating stick 2
It is connected to negative pressure device 3.
