Description

The structure of swallow type endoscope

Technical field

The present invention relates to a kind of structure of swallow type endoscope, particularly a kind of swallow type endoscope with double Shell design.

Background technology

The tradition endoscope apparatus, it is with a device for capturing miniature image, as CCD (Charge CoupledDevice, Charged Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor, partly lead complementary oxidized metal) be arranged at a body end with optical fiber, an end that body is provided with image capture unit stretches in the human body, can illuminate human organ inside by optical fiber, and pass a main control system back by the inner image of image capture unit acquisition organ and with signal, be that image is shown on the screen by main control system with conversion of signals again, observe the organ internal state by this; Yet traditional cannula type endoscope is for the small intestinal of path complexity and length long (about seven meters), its operating difficulties degree is high, and can cause patient's utmost point discomfort, very might damage intestinal, therefore, development in recent years goes out a kind of swallow type endoscope (claiming capsular endoscope again), its external form is just like capsule (stock size is about about diameter 11mmx length 26mm), with image capture unit, illuminator, devices such as signal processing apparatus are arranged in it, the patient swallows behind the endoscope, can take the intestines and stomach digestion is the image of system, and signal is reached a wireless transmission accepter store, the endoscope of capsule shape then can excrete along the wriggling of the intestines and stomach.

Yet, swallow type endoscope is to rely on intestinal peristalsis promoting and advance, when intestinal stops wriggling or intestinal obstructions, endoscope takes place and is stuck in the interior situation of intestinal in regular meeting, restriction based on supply of electric power, the shooting time of general swallow type endoscope is about eight hours, in the time of can't advancing if the capsule-type endoscope is stuck, often causes power drain and can't finish inspection; Secondly, the external form symmetry of general swallow type endoscope, at with the patent of swallow type endoscope structurally associated, more representative patent as, No. 4278077 Medical camera system of United States Patent (USP) (as shown in Figure 1), No. 6776165 Magneticnavigation system for diagnosis, biopsy and drug delivery vehicles (as shown in Figure 2), the early stage No. 20030167000 Miniature ingestible capsule (as shown in Figure 3) that disclose, Chinese patent application number No. 03100098.3 capsular endoscope (as shown in Figure 4), the capsular endoscope (as shown in Figure 5) of No. 092214583 tool rotatable image sensing module of TaiWan, China number of patent application, the capsular endoscope (as shown in Figure 6) of No. 093216785 tool multi-chip module, the capsular endoscope (as shown in Figure 7) of No. 092214586 movable fin keel of tool, take a broad view of technological means that aforementioned each patent provides as can be known, its emphasis is at image capture mostly, technology such as image focusing improve, as for its structure, then only has single housing, and the external form of described housing is to be the symmetric capsule shape in two ends, wherein, structure is comparatively special, the capsular endoscope of the movable fin keel of No. 092214586 tool as shown in Figure 7, it is to be provided with movablefin keel 150outside capsule shells 110, by controlmagnetic area 153, the sense of current ofmagnetized area 112, the folding of may command activityfin keel 150, reach the purpose of describedcapsular endoscope 100 direct of travels of control by this, so even so, describedcapsular endoscope 100 is still the dependence intestinal peristalsis promoting and advances, and the sharp-pointed tail end of its movablefin keel 150, on the contrary intestinal walls is existed the injury of potentiality, even to the mobile obstruction that causes ofcapsular endoscope 100.
