Abstract

Disclosed is a one-off anoscope for hemorrhoid artery ligation, consisting of a body, a handle and an internal embolus. The invention is characterized in that the body length is 10-12 cm and the body diameter is 26-30 cm; the front end of the body is a closed half-globe end and the back end of the body is provided with an operation window whose width is one third of the circumference and whose long shaft is 4 cm in length; the upper end and the lower end of the operation window are both shaped like a circular arc; an inverted parabolic break which is arranged at the tail part of the body at the same side as the operation window is 1-2 cm high and 1.2-1.5 cm wide, allowing fingers to be more deep into the body; a 3.5-4.0 cm perfect ring is arranged between the operation window and the break. In treating internal hemorrhoid the small-diameter anoscope body and the internal embolus can be easily sent into the anus, then the embolus is drawn out, and the front operation window is just used to look for and ligate the hemorrhoid artery, while the circular tail part can be used to support an anal channel and to shield a thick anal cushion and the break at the tail part is used to provide space for fingers operation; the body is injection-molded by medical non-toxic transparent plastic material, facilitating observations in operation.

Description

Disposable anoscope for hemorrhoid artery ligation

Technical field

The present invention relates to a kind of medical apparatus and instruments, the disposable anoscope that uses when being specifically related to utilize Doppler to guide hemorrhoid artery ligation.

Background technology

Now the apparatus of the hemorrhoid artery ligation in market is a kind of doppler transducer and the anoscope anoscope that combines, its shortcoming is: 1 front opening is too narrow and small, can not look at mucous membrane of rectum straight during use, come risk to surgical band, particularly when the mucous membrane of rectum bleed bottom, be not easy to find, found also intractable, can only use other modes again instead and remedy; 2 can not suspend mucous membrane of rectum in midair when the ligation tremulous pulse; 3 can not directly tie a knot with hands, must knot pusher knotting, not only inconvenience but also increase difficulty and risk; 4 ultrasonic probes and action pane be not or not same plane, and blood vessel that the result detects and ligation position are not same positions, can not reach the purpose of accurate ligation; 5 owing to the disposable use of ultrasonic probe, involves great expense.

Also the someone uses Johnson Co. to produce to be used to the seam that carries out mucous membrane of rectum ring cutting stitching art to prick device and does this operation, and shortcoming is obvious especially: 1 mirror body diameter is longer, and local anaesthesia is difficult to successfully; It is gap that 2 whole seams are pricked device one side, and operation needs other drag hook just can appear operating field, also needs skilled assistant to cooperate and finishes operation.

Summary of the invention

The present invention overcomes above shortcoming, cheap, patient's no pain is provided, is used for the disposable anoscope of hemorrhoid artery ligation, and this product is realized in the following way: this anoscope mainly is made up of mirror body, handle, interior bolt.

The mirror body is for being about 10-12cm, diameter is the tube chamber of 26-30mm, be shorter in length than 10cm then at the buttocks ditch depth, the patient of anal canal length is not easy to operate, and length then there is no need greater than 12cm, increases the risk of damage rectum, diameter then is difficult to carry out local anesthesia greater than 30mm, patient's pain is damaged anal canal easily, less than 26mm operating difficulties then; The mirror body for the hemispherical of sealing, had both conveniently entered anus foremost, supported a good visual field and working place for operation window again;

There is an operation window hemispherical back in sealing, it is 1/3 of mirror body Zhou Jing for width, the hollow out breach of the about 4cm of major axis, the upper and lower side of this operation window is circular arc, the hemispherical of its upper end circular arc and sealing is tangent foremost, when being convenient to from anal canal, withdraw from smoothly, the edge of operation window does not damage the anal canal wall, the arc abdomen of lower end circular arc is relative with the arc abdomen of upper end circular arc, stop that lax mucous membrane of rectum comes into view, increase the valid function visual field, also be convenient to operating theater instruments and finger and be bent into the anal canal from this operation window and operate;

The anoscope tail end that is located on mirror body one side with operation window has a gap, it is inverted parabola shaped that this gap becomes, this gap height is 1-2cm, the widest part is 1.2-1.5cm, feasible finger can go deep into the mirror body more, thereby can reach operation window smoothly, and gap height, wide too small then finger are not easy to enter, width is excessive then to be unfavorable for supporting influencing operation technique by anal canal; The mirror body that the long complete annular of 3.5-4.0cm is arranged between operation window and gap, human body anal canal tooth trace is to the about 3-4cm of anus edge length, even can guarantee that like this anal canal is long, the patient of buttocks ditch depth, the length of complete annular mirror body adds that the length of opening position mirror body also can support anal canal, appears surgical field of view smoothly;

Handle becomes miter angle to tilt to stretch out with plane, mirror body tail end place, carry out grasping when making things convenient for the doctor to extract anoscope.

The general interior bolt form of interior bolt and present anoscope is similar, does not repeat them here.

This mirror body adopts the injection mo(u)lding of medical poisonless transparent plastic material, and the enough clinical safeties of intensity use, and transparent mirror body is beneficial to the observation needs of operation.

The specific embodiment

Anoscope is coated paraffin oil during use, interior bolt is inserted anus with the anoscope body, buttress handle then on the other hand, withdraw from interior bolt on the other hand, can know in operation window this moment and see the above mucous membrane of rectum of pectinate line, anal canal and plump blood stasis are blocked and are being anoscope annular section outside, the near-end arc of operation window can appear longer mucous membrane of rectum in the vertical, reducing plump or lax mucous membrane of rectum simultaneously charges in the mirror body cavity, this moment, doppler transducer can be surveyed the hemorrhoid tremulous pulse on a good face in the visual field, after detecting artery position, use suture accurately to stitch bundle in this position, blocking-up hemorrhoid tremulous pulse, because operation window only accounts for 1/3 of mirror body Zhou Jing, the mirror body cavity provides competent working place for operation; If tail end does not have gap, suture location is higher or doctor's finger is shorter, then to enter the degree of depth not enough for doctor finger, other apparatus of action need is auxiliary to carry out, as tie a knot and need to rely on knot pusher, directly tie a knot convenient and swiftly, reliable not as finger, and the gap of tail end makes doctor's finger arrive operation window smoothly, can conveniently directly tie a knot, perhaps do operations such as palpation, hemostasis by compression with hands; Suspend mucous membrane of rectum if desired in midair, the operation window that major axis reaches 4cm also can handled easily; If run into hematoma under the mucosa (very common), also can conveniently handle.

This invention is easy to use, and a doctor can finish operation in the simple help of unfamiliar nurse.

In addition, because this seam is pricked the fine mucous membrane of rectum that appears of device energy, when the hemorrhage of rectum seam is pricked operations such as art, injection of sclerosing agent, searching anal fistula internal orifice, operation, use also very convenient.

The present invention has simple in structure. With low cost, avoid the characteristics such as cross-infection, be applicable to Produce in enormous quantities, promote, use.
