Description
Technical Field
The utility model relates to a medical apparatus of gynaecology, in particular to electricity is cut side vision hysteroscope.
Background
In gynecological operation, uterine cavity occupying lesion such as uterine cavity polyp, uterine submucosal myoma, residual placenta and the like can be directly treated by operation through a hysteroscope. For endometrial biopsy, adhesion release, mediastinal uterus and the like, the surgical treatment can also be directly carried out through a hysteroscope.
Hysteroscopes include direct-view hysteroscopes and side-view hysteroscopes. The hysteroscope, in which an eyepiece for observation of a doctor and an objective lens for observing a tissue object are positioned on the same axis, is called a direct-viewing hysteroscope. The hysteroscope, in which the eyepiece for observing by the doctor and the objective lens for observing the tissue are not positioned on the same axis, is called a side-view hysteroscope. In the side-looking hysteroscope, the included angle between the axis of the eyepiece and the axis of the objective lens can be an acute angle or a right angle.
Three surgical instruments matched with the side-looking hysteroscope are provided, specifically an electric cutting instrument, a cold knife instrument and a planing knife system. Electrical cutting instruments include monopolar electrical cutting and bipolar electrical cutting. Based on the characteristics of the electric cutting instrument, when the electric cutting instrument is used, the matched instrument is complex, so that great inconvenience is brought to the use.
In addition, the existing side-looking hysteroscope cannot be compatible with more than two surgical instruments. Although a part of the side-view hysteroscope can be compatible with more than two surgical instruments, after one surgical instrument is used, the surgical instrument needs to be taken out, and the other surgical instrument needs to be inserted into the hysteroscope; the defect that more than two surgical instruments cannot be used simultaneously and compatibly exists, and the efficiency of the operation is reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an electricity is cut side vision hysteroscope in order to overcome the above-mentioned defect that prior art exists.
The utility model discloses an above-mentioned technical problem is solved through following technical scheme:
an electric-cutting side-looking hysteroscope comprises a scope body, wherein the scope body comprises a front section part and a rear section part, and the front section part of the scope body is sleeved with a sheath; a side-view mirror body is arranged at the rear section part of the mirror body; the sheath is internally provided with an electric cutter and a supporting rod for supporting the electric cutter, the supporting rod and the electric cutter are both positioned below the front section of the endoscope body, and the electric cutter and the supporting rod are both distributed along the axial direction of the sheath; the supporting rod and the electric knife are both arranged at the rear section of the mirror body in a penetrating way; the rear end of the rear section part of the mirror body is provided with a mirror bridge; the supporting rod and the electric knife are arranged in the bridge in a penetrating way; the rear end of the bridge is provided with an electric cutter working hand piece which can control the electric cutter to slide along the axial direction of the sheath.
The electrotome is arranged outside the supporting rod, and the supporting rod is arranged between the front section of the mirror body and the electrotome.
