Description

A kind of Medical cervical internal orifice cutter head

Technical field

The present invention relates to medical device industry technical field more particularly to a kind of Medical cervical internal orifice cutter heads.

Background technology

Currently, the excision extension of traditional conization art includes ectocervical lesion outer 3-5mm, depth 7mm group It knits and cervical canal depth 1-2cm, thickness 7mm is organized.Used tradition LEEP cutter heads also include cervical orifice cutter head and uterine neck internal orifice Cutter head, by taking cervical orifice cutter head as an example, sectioned coil width radial line A is of different sizes, including 10mm, 20mm, 25mm, 35mm etc., sectioned coil height value also have different size, including 5mm, 10mm, 20mm etc., are needed much larger than operation The tissue depth to be cut off.It can be seen that in traditional conization art, patient oneself is needed to control the depth of excision, a side It is excessive that face is easy to happen resection organization's depth, leads to the adverse consequences such as surface of a wound bleeding, late wounds bleeding, incompetence,cervical； On the other hand there are the depth difference of different patients excision, lead to the inhomogeneity of surgical effect.

Invention content

The purpose of the present invention is to solve disadvantage existing in the prior art, and a kind of excision depth proposed it is accurate, More accurate, wound smaller protects the Medical cervical of the cervical cempetence of patient as far as possible while treating precancerous lesions of uterine cervix Internal orifice cutter head.

To achieve the goals above, present invention employs following technical solutions：

A kind of Medical cervical internal orifice cutter head, including bit body, the bit body include the internal rotation for carrying heat conducting bar The front end side of bull stick, the swingle is equipped with sectioned coil, and the sectioned coil is in arc-shaped, the sectioned coil inside End is equipped with cutter head handle, and the cutter head handle is insulation not Heat Conduction Material；The rear end of the swingle is connected with by thread head Conducting rod, the conducting rod is internally provided with two lines road, and does not communicate with each other, the swingle close to the thread head one End cap, which is connected to, holds pad.

Preferably, the width of the sectioned coil is fixed as 20mm, and the height of the sectioned coil is fixed as 3mm.

Preferably, the length of a diameter of 2.5mm of the conducting rod, exposed parts are 18mm, the thread head covering Partial length is 2mm.

Preferably, the thread head uses Design of Screw Thread.

Preferably, the pad of holding is the athermanous cushion material that insulate.

Compared with prior art, beneficial effects of the present invention are：A kind of Medical cervical internal orifice cutter head of the present invention, packet Bit body is included, the bit body includes the internal swingle for carrying heat conducting bar, and the front end side of the swingle is equipped with Sectioned coil, the sectioned coil are in arc-shaped, and the sectioned coil medial end is equipped with cutter head handle, and the cutter head handle is insulation Not Heat Conduction Material；The rear end of the swingle is connected with conducting rod by thread head, and the conducting rod is internally provided with two Circuit, and do not communicate with each other, the swingle is socketed with close to one end of the thread head and holds pad；The present invention uses above-mentioned knot Structure, it can be ensured that it is 20mm that cervical canal, which cuts off depth, and excision thickness is 2-3mm, can be excessive, local to avoid depth is cut off in operation The complication such as more, the damage cervical cempetence of surface of a wound bleeding；It can also reduce simultaneously and cause to cut off depth because different operative doctors operate Difference leads to the lack of uniformity of therapeutic effect, simplify cervicectomy it is intelligent, homogenization, standardize.

Description of the drawings

Fig. 1 is the stereogram of the present invention；

Fig. 2 is the front view of Fig. 1；

In figure：Pad, 5 thread heads, 6 conducting rods are held in 1 sectioned coil, 2 cutter head handles, 3 swingles, 4.

Specific implementation mode

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

- Fig. 2 referring to Fig.1, a kind of Medical cervical internal orifice cutter head, including bit body, the bit body include internal band There is the swingle 3 of heat conducting bar, wherein a diameter of 3.9mm of the swingle 3, and the surface of the swingle 3 is covered with insulation and does not lead Hot material, safe and reliable in operation in this way, the front end side of the swingle 3 is equipped with sectioned coil 1, the sectioned coil 1 is in arc-shaped, and in the present embodiment, the width of the sectioned coil 1 is fixed as 20mm, and the height of the sectioned coil 1 is fixed as 3mm can ensure that cervical canal excision depth is 20mm in this way, and excision thickness is 2-3mm, can be to avoid excision depth mistake in operation Greatly, the complication such as more, damage cervical cempetence of local woanded surface bleeding；1 medial end of the sectioned coil is equipped with cutter head handle 2, described Cutter head handle 2 is simple insulation not Heat Conduction Material, is used to prevent above-mentioned sectioned coil 1 from entering cervical canal so too deep；The rotation The rear end of bull stick 3 is connected with conducting rod 6 by thread head 5, and the thread head 5 uses Design of Screw Thread, which is used for will Conducting rod 6 is connect with swingle 3, plays connection function, and the connection electric wire (not shown) rotation at rear is driven when swingle 3 being made to rotate Turn, avoiding the two from being detached from leads to current interruptions, and the conducting rod 6 is internally provided with two lines road, and does not communicate with each other, and protects in this way Demonstrate,prove that entire cutter head circuit is not short-circuit, and the swingle 3 is socketed with close to one end of the thread head 5 and holds pad 4, in the present embodiment In, the pad 4 of holding is the athermanous cushion material that insulate, and surface increases coarse performance design, it is ensured that is performed the operation in operation Doctor reduces the sense of discomfort of patient's finger to the control in entire cutter head direction, rotating speed and dynamics.

Specifically, a diameter of 2.5mm of the conducting rod 6, the length of exposed parts is 18mm, and the thread head 5 covers The length of cover is 2mm, for the not long 130mm of Heat Conduction Material covering part of insulating, makes its safe operation, reliable in this way.

In conclusion the novel cervical collar extension cutter head is different by epithelium of cervix uteri and muscle layer tissue embryo origin, according to non- Autologous tissue barrier theory principle proposes that uterine neck LEEP resection knives, the excision extension of operation include：Ectocervical outer surface The tissue of depth 3mm and the tissue of cervical canal depth 20mm width 3mm so that excision depth is accurate, more accurate, wound more It is small.

The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
